Hijri Date Converter

What Is the Hijri Calendar?

The Hijri calendar (the Islamic calendar) is a lunar calendar that takes the Prophet Muhammad's migration (Hijra) from Mecca to Medina in 622 CE as its starting point (year 1 AH). Each month is 29 or 30 days, and each year is about 354 days. Because the lunar year is roughly 11 days shorter than the solar (Gregorian) year, Islamic months such as Ramadan move back about 10-11 days each Gregorian year. This Hijri date converter handles the full Hijri Gregorian conversion in both directions using the standard tabular Islamic calendar, so you never have to do the maths by hand.

Working as both a Hijri Gregorian calculator and a Gregorian calendar calculator, the tool lets you switch direction with one tap. It is useful for finding birthdays, anniversaries and historical events on the other calendar, and for planning religious observances whose Gregorian date shifts every year.

The 12 Months of the Hijri Calendar

A Gregorian to Hijri conversion returns one of these 12 lunar months. The table below lists each month with its typical length:

Hijri to Gregorian Converter: How to Convert Dates

Used as a Hijri to Gregorian converter or a Hijri calendar converter, the tool turns any date into its equivalent in seconds:

1. Pick a direction: Choose "Gregorian to Hijri" or "Hijri to Gregorian".
2. Enter the date: For Gregorian, pick a date; for Hijri, select the day, month and year.
3. Press Convert: The equivalent date in the other calendar is shown, along with the weekday and month name.
4. Use Today: Press "Today" to instantly get today's Hijri date.

What Is Today's Hijri Date?

One of the most common questions is simply: what is today's Hijri date? When you open this page, today's date is loaded automatically and converted, so you immediately see the current Hijri year, month and day. You can also press the "Today" button at any time to refresh it. This is handy for dating letters and documents in the Islamic calendar, for knowing how far into a sacred month you are, or for confirming whether a special day such as a Friday in Ramadan has arrived. Because the tool runs entirely in your browser, the result is instant and stays accurate as the day rolls over.

The Difference Between the Gregorian and Hijri Calendars

The Gregorian calendar is solar (365.25 days per year); the Hijri calendar is lunar (about 354 days per year). Over time the two drift: 33 Gregorian years correspond to roughly 34 Hijri years. This is why a fixed Hijri date (such as 1 Ramadan) falls about 10-11 days earlier in the Gregorian calendar each year, cycling through all seasons over about 33 years. Knowing this Hijri Gregorian relationship explains why Ramadan can fall in summer one decade and in winter the next.

When to Use a Hijri Gregorian Calculator

A Hijri Gregorian calculator is useful far beyond religious planning. Here are common situations where converting between the two calendars matters:

• Official documents: Birth, marriage and historical records in many countries are kept in the Islamic calendar; converting to Gregorian makes them easy to read internationally.
• Religious observances: Ramadan, the two Eids, Ashura and Mawlid all fall on fixed lunar dates but shifting Gregorian ones, so a converter is the quickest way to plan ahead.
• Anniversaries and birthdays: If you celebrate a lunar-calendar birthday, the tool finds its Gregorian date for any year.
• Travel and Hajj planning: Pilgrimage and Umrah seasons follow the Islamic calendar, so a quick conversion helps you book at the right time.
• Historical research: Dates in classical Islamic sources are given in the lunar calendar; converting them places events on a familiar timeline.

Important Islamic Days

The tool's "Upcoming Islamic Days" section lists the next observances and how many days remain. The main religious days on the lunar calendar are:

• Islamic New Year — 1 Muharram
• Day of Ashura — 10 Muharram
• Mawlid (Prophet's birthday) — 12 Rabi al-Awwal
• Isra and Miraj — 27 Rajab
• Start of Ramadan — 1 Ramadan
• Laylat al-Qadr — 27 Ramadan
• Eid al-Fitr — 1 Shawwal
• Day of Arafah — 9 Dhu al-Hijjah
• Eid al-Adha — 10 Dhu al-Hijjah

Note: exact observance dates can vary by country and community, since some follow astronomical calculation and others local moon sighting. This converter uses the tabular Islamic calendar for a consistent reference.
