Islamic Calendar 2026: Hijri Months and Key Dates

How the Islamic (Hijri) calendar works

The Islamic calendar, also called the Hijri calendar, is a lunar calendar. That single word, lunar, explains almost everything about how it behaves. Instead of tracking the earth's journey around the sun the way the Gregorian calendar you use for work and school does, the Hijri calendar tracks the moon. Each month begins with the sighting of a new crescent moon, runs through the moon's phases, and ends as the next crescent appears. This is why the Islamic calendar 2026 does not sit neatly on top of the ordinary year you know; it moves to a rhythm of its own.

A single lunar month, the time from one new moon to the next, is roughly 29 and a half days. Since you cannot have half a day on a calendar, each Hijri month is either 29 or 30 days long, and which one it is depends on when the next crescent is actually seen. Twelve of these months make one Hijri year, and that adds up to about 354 days. Hold that number in mind, because the difference between 354 and the 365 days of the solar year is the reason every Islamic date seems to move.

The calendar is called Hijri because it counts years from the Hijrah, the migration of the Prophet Muhammad, peace be upon him, from Mecca to Medina. That event was chosen as year one. So when you see a year written as 1447 AH or 1448 AH, the letters AH stand for the Latin phrase meaning "in the year of the Hijrah," and the number tells you how many lunar years have passed since that migration. During the Gregorian year 2026, the Hijri year changes over: the year starts inside 1447 AH, and around the middle of the year it becomes 1448 AH.

There is a second point worth understanding early, because it causes a lot of the confusion people feel about Islamic dates. In the Hijri calendar the day begins at sunset, not at midnight. When you hear that a certain night is the first night of Ramadan or the night of an Eid, that night starts the evening before the daytime you would mark on a Gregorian calendar. This is why the night comes before the day in Islamic practice, and it is why the special nights of the year, like the last ten nights of Ramadan, are counted from sunset onward.

Why Islamic dates fall earlier each year

Here is the practical effect that touches every family. A lunar year of about 354 days is roughly 11 days shorter than a solar year of about 365 days. Because the Hijri calendar runs 11 days short each time around, every Islamic occasion arrives about 10 to 12 days earlier on the Gregorian calendar than it did the year before. Ramadan is the clearest example. If it begins in the middle of February one year, the following year it starts in early February, and the year after that in late January, creeping backward through the ordinary calendar year by year.

This drift is not a flaw. It is a feature many Muslims come to love. Over a span of roughly 33 years, a fixed Hijri date makes a full loop through all the seasons. Ramadan will fall in winter for some years, then spring, then the long days of summer, then autumn, and back again. That means every believer, across a lifetime, experiences fasting in short winter days and in long summer days alike. The moon keeps the worship tied to a cycle that is the same everywhere on earth, rather than fixed to one hemisphere's seasons.

It also explains why you cannot memorize an Islamic date once and reuse it forever the way you might remember that a national holiday always falls on the same calendar day. There is no permanent "Ramadan is in this month" rule you can lean on. The month you fast in this year will have shifted by next year. For anyone trying to plan travel, work leave, school, or family gatherings around the Islamic year, this shifting is exactly why a calendar that does the conversion for you is so useful, and why guessing from last year's dates leads people astray.

One more consequence is worth naming. Because the drift is gradual and the exact start of each month depends on the moon, you will sometimes see two printed calendars disagree by a day for the same occasion. Neither is being careless. They are simply built on slightly different assumptions about where and when the crescent will be visible. This is normal, and it is part of why the final word on any date belongs to the moon sighting and the local authority, not to the piece of paper or the app screen.

The twelve months of the Hijri calendar

The Hijri year has twelve months, each 29 or 30 days long. Their order never changes, and knowing them in sequence makes the whole calendar far easier to picture. Below is each month in order, with the meaning commonly associated with its name and a note on what it is known for. A gentle caution on the meanings: these names come from old Arabic and their origins are traditionally explained in particular ways, so treat the meanings as the widely repeated understanding rather than as precise dictionary definitions.

• 1. Muharram is commonly understood to mean "forbidden" or "sacred," because fighting was traditionally prohibited during it. It is one of the four sacred months and the first month of the Hijri year. The Day of Ashura falls on its tenth day.
• 2. Safar is often linked to a word meaning "empty," said to describe homes left empty as people set out to travel or seek provision after the sacred month had passed.
• 3. Rabi al-Awwal means, in the common telling, "the first spring." It is the month in which many Muslims note the birth of the Prophet Muhammad, peace be upon him.
• 4. Rabi al-Thani, also written Rabi al-Akhir, means "the second spring," the companion month to the one before it.
• 5. Jumada al-Awwal is traditionally tied to a root suggesting dryness or frozen ground, describing a dry, cold time of year when the names were first given.
• 6. Jumada al-Thani, also written Jumada al-Akhir, is "the second Jumada," paired with the month before it.
• 7. Rajab comes from a root connected to respect or awe. It is one of the four sacred months and is treated with special regard.
• 8. Sha'ban is often explained as coming from a word meaning "to scatter" or "to disperse," describing people spreading out in search of water. It leads directly into Ramadan.
• 9. Ramadan is traditionally linked to intense heat, from a root describing scorching ground. It is the month of obligatory fasting and the month in which the Quran began to be revealed.
• 10. Shawwal is often tied to a root meaning "to raise" or "to lift." Its first day is Eid al-Fitr, the celebration that ends the month of fasting.
• 11. Dhul Qa'dah means, in the common explanation, "the one of sitting" or "of truce," a month of rest when travel and fighting traditionally paused. It is one of the four sacred months.
• 12. Dhul Hijjah means "the one of the pilgrimage." It is the month of Hajj, it contains the Day of Arafah and Eid al-Adha, and it is one of the four sacred months.

If you learn just three of these by heart, make them Ramadan, Shawwal, and Dhul Hijjah, because those three carry the occasions your year revolves around: fasting, the first Eid, and the pilgrimage with the second Eid. The rest will settle into place naturally as you watch a Hijri calendar over a few months. Seeing today's Hijri date every day, next to the ordinary date, is the fastest way to internalize the order without any deliberate memorizing.

The four sacred months

Among the twelve, four months are given a special status and are called the sacred months. The Quran itself states that the number of months is twelve, and that of them four are sacred (see Quran 9:36). These four are Dhul Qa'dah, Dhul Hijjah, Muharram, and Rajab. Three of them run in sequence, Dhul Qa'dah, Dhul Hijjah, and Muharram, wrapping around the turn of the Hijri year, while Rajab stands on its own earlier in the year.

In these months, fighting was traditionally forbidden and wrongdoing was considered especially grave. Many Muslims treat them as a time to be more careful with their conduct and more attentive to worship, and some choose to fast voluntary days within them. The sacred months are also tied to the two great journeys of the year: Dhul Qa'dah and Dhul Hijjah surround the season of Hajj, and Muharram opens the new Hijri year. Understanding which months are sacred adds a layer of meaning to the calendar that goes well beyond simply knowing the dates.

If you want to act on this, the simplest step is to notice when a sacred month begins and to treat it as a small invitation: a little more remembrance, a little more restraint, perhaps a voluntary fast or two. For the specific rulings on what is recommended in each month, follow qualified scholars and your local teachers rather than piecing it together yourself, since the details carry differences of opinion that a short guide cannot settle.

Key Islamic dates in 2026

Below are the major Islamic occasions that fall within the Gregorian year 2026, in the order they arrive, each with an approximate Gregorian date. Read the word "approximate" seriously. Every date here is an estimate based on astronomical calculation, and the confirmed date for your area will come from the sighting of the moon and the ruling of your local authority. A date can move by a day in either direction, and it can differ from one country to the next. Use these to plan, and confirm each one as it approaches.

Ramadan (expected from around mid February 2026)

Ramadan, the ninth month, is the month of obligatory daily fasting from dawn until sunset for those who are able. In 2026 it is expected to begin around the middle of February, with many calendars pointing to on or near the 18th of February 2026, and to run for either 29 or 30 days into the second half of March. Because the first day depends on sighting the crescent that marks the start of the month, the actual beginning may fall a day before or after that estimate. Families usually watch for the announcement on the evening the crescent is due. For a fuller look at how this date is worked out, see our guide on when Ramadan 2026 falls.

Laylatul Qadr (sought in the last ten nights of Ramadan)

Laylatul Qadr, the Night of Power, is described as better than a thousand months, and it falls somewhere within the last ten nights of Ramadan. It is not tied to one fixed Gregorian date. In 2026, since Ramadan is expected to begin around mid February, the last ten nights would fall roughly across the second and third weeks of March 2026. Muslims are encouraged to seek this night especially on the odd nights of the last ten, with the 27th night often given particular attention, though the exact night is not certain and is part of the wisdom of seeking it across all ten. To prepare for it, read our guide on Laylatul Qadr and how to spend it.

Eid al-Fitr (expected around March 20, 2026)

Eid al-Fitr is the celebration that marks the end of Ramadan and the first day of the month of Shawwal. In 2026 it is expected around the 20th of March, immediately after the final day of fasting. Since it depends on the sighting of the Shawwal crescent, it may land a day earlier or later than the estimate, and it can differ between regions. The day begins with a special Eid prayer in congregation, usually in the morning, preceded by a charitable payment called Zakat al-Fitr that is given before the prayer so that those in need can share in the day.

Hajj and Eid al-Adha (expected in late May 2026)

The Hajj, the annual pilgrimage to Mecca, takes place in the month of Dhul Hijjah. Its central days, including the Day of Arafah on the ninth of the month, are expected around the end of May 2026. Eid al-Adha, the second Eid of the year, falls on the tenth of Dhul Hijjah, expected on or around the 27th of May 2026. This Eid commemorates the willingness of the Prophet Ibrahim to sacrifice for the sake of Allah, and it is marked by the Eid prayer and, for those able, the sacrifice of an animal whose meat is shared with family, neighbors, and the poor. As with the others, these dates are estimates that hinge on the sighting of the Dhul Hijjah crescent.

Islamic New Year: 1 Muharram 1448 (expected in mid to late June 2026)

The first of Muharram marks the start of a new Hijri year. During 2026 the Hijri year turns from 1447 to 1448, and the first day of Muharram 1448 is expected around the middle of June 2026, roughly on or near the 16th or 17th. It is a quiet turning point rather than a festival of celebration, and many Muslims simply take note of it and reflect on the year behind and ahead. There are differences in how the day is observed, so follow your local guidance.

Day of Ashura: 10 Muharram 1448 (expected in late June 2026)

The Day of Ashura falls on the tenth of Muharram, expected around the 25th or 26th of June 2026, following the start of the new Hijri year. Many Muslims observe a voluntary fast on this day, and some add the day before or after it. Its significance and the ways it is observed carry differences across the community, so for the specific practice you follow, take your guidance from qualified scholars and your local teachers.

Mawlid an-Nabi: 12 Rabi al-Awwal (noted by many, expected in late August 2026)

The twelfth of Rabi al-Awwal is the date on which many Muslims note the birth of the Prophet Muhammad, peace be upon him. In 2026 it is expected around the end of August, roughly the 24th to 26th of the month. Muslims differ in whether and how they mark this occasion, and this guide notes it simply as a date on the calendar without ruling on the practice. As always, the confirmed date depends on the moon, and questions of observance are best taken to knowledgeable scholars.

Notice how the year unfolds. It opens still inside the Hijri year 1447, moves through Ramadan and the first Eid in late winter and early spring, reaches the Hajj and the second Eid in late spring, turns over into the new Hijri year 1448 in the summer, and closes the way it always does, with the moon deciding each step. Every one of these rows is a planning aid, not a fixed appointment. Pencil them in, then confirm each as the crescent is sought.

Why every 2026 date is an estimate

It is worth pausing on this point on its own, because it is the single most important thing to understand about an Islamic calendar, and the place where well-meaning guides most often mislead. Any Gregorian date printed for an Islamic occasion is a prediction. It is produced by calculating where the new crescent moon will be and estimating whether it will be visible. That calculation is good, but the calendar in Islam has traditionally begun a month when the crescent is actually seen, and visibility can differ from the calculation by a day.

Several things push the real date away from the printed one. The crescent might be born below the horizon at sunset in one region and just above it in another, so one country sees it and another does not on the same evening. Weather can hide the moon where it would otherwise be visible. Different authorities apply different criteria for what counts as a confirmed sighting, and some communities follow the sighting in a particular land while others rely on the local horizon. None of this is disorder. It is simply what happens when a calendar is tied to a real event in the sky rather than to arithmetic alone.

What this means for you is straightforward. Use the estimates in this guide, and any calendar or app, to plan ahead: to book leave for Eid, to arrange your Ramadan, to prepare for the last ten nights. Then, as each occasion draws near, confirm the actual date through your local mosque, your community's moon-sighting body, or a trusted authority you already follow. Do not treat a printed date as final, and do not be unsettled when the confirmed day lands a day off from what a calendar showed. That gap is expected, and following your local authority on it is the sound way to proceed.

How to track dates and never miss a night or fast

Knowing how the calendar works is one half of the task. The other half is simply not letting an important night or fast slip past while ordinary life fills your attention. The occasions that matter most are easy to miss precisely because they move each year and do not sit on the fixed calendar your phone and your work already run on. Here is a practical approach to staying ahead of them.

Keep the Hijri date in front of you daily. The best defense against surprise is seeing today's Islamic date every day, next to the ordinary date. When you watch the Hijri months turn over, you develop a feel for what is coming. You notice Sha'ban arriving and know Ramadan is near. You see the first days of Dhul Hijjah and remember the Day of Arafah and the fasts that many keep before Eid al-Adha. A calendar you glance at daily makes the year legible.

Watch the run-up to Ramadan. Since Ramadan reshapes a whole month of your life, it deserves early attention. As Sha'ban progresses, start preparing: plan your suhoor and iftar routine, sort out any leave from work, and get ready for the shift in sleep. Do not wait for the first night to catch you off guard. Our guide on when Ramadan 2026 falls walks through the timing in more detail.

Mark the last ten nights early. Laylatul Qadr is the single night most worth not missing, and it hides within the last ten nights of Ramadan. The mistake many people make is arriving at the last ten nights already tired and unprepared. Decide in advance how you will free up those nights, and treat the odd nights especially seriously. A reminder set for the twentieth of Ramadan, before the last ten begin, is worth more than any other single note in your year.

Note the voluntary fasting days. Beyond Ramadan, there are days many Muslims choose to fast, such as the Day of Ashura in Muharram and the Day of Arafah in Dhul Hijjah for those not on Hajj. These are easy to miss because they are voluntary and move each year. If you intend to keep them, a calendar that flags them ahead of time turns a good intention into an action.

Confirm each date locally as it nears. Because every printed date is an estimate, build the habit of checking the confirmed date with your local mosque or authority in the final days before each occasion. This is especially true for the start of Ramadan and for both Eids, where a day's difference changes when you fast and when you celebrate.

Do all of this without an app if you like; a wall calendar and a few reminders will carry you a long way. But the reason so many households keep an Islamic calendar on their phone is that it does the counting, the conversion, and the reminding for you, quietly, so that a busy week never costs you a night you meant to keep.

How Niyyara's Islamic calendar helps

Understanding the Hijri calendar is satisfying, but living by it is easier with a little help, and that is exactly what Niyyara is built to give, without costing you anything. Niyyara is a free, private, ad-free companion for a practicing Muslim, and its Islamic calendar is designed to take the counting off your shoulders so you can simply be present for the year as it comes.

Inside the app you can see today's Hijri date alongside the ordinary date, so the Islamic year is always in view rather than something you have to look up. You can look ahead through the coming months and see the important occasions marked, from Ramadan and the last ten nights to the two Eids, the Day of Arafah, Ashura, and the turn of the Hijri year. Because the calendar sits next to the rest of the app, the same tool that shows you the date also gives you accurate prayer times for your location, the azan when each prayer enters, an exact Qibla compass, the full Quran with audio, everyday duas, the 99 names of Allah, a tasbih for remembrance, and a worship tracker to help you keep your consistency through Ramadan and beyond.

And because it is completely free, with no subscriptions and no ads, there is nothing standing between you and a reminder that matters. Worship should never feel like a product being sold to you. Niyyara stays out of the way and simply helps you keep the year: to know the date, to see what is coming, and to be ready for the nights and fasts you do not want to miss. Set your location once, and let it carry the calendar so your attention can stay on the worship itself.

The Islamic calendar 2026 will move the way it always does, a little earlier than last year, each month opening with the moon. You now have the whole picture: how the Hijri year works, why it drifts, the twelve months in order, the four sacred months, and the major dates of the year with their approximate places on the ordinary calendar. Keep the estimates for planning, confirm each date locally as it arrives, and let a good calendar carry the rest. May Allah accept your worship through every month of the year.
