The Hijri calendar, also known as the Islamic calendar, is the calendar used by Muslims to determine important religious dates and events throughout the year.

It is used to identify Islamic months, fasting days, Ramadan, Eid celebrations, Hajj, and many other significant occasions.

Unlike the Gregorian calendar used in most countries today, the Hijri calendar follows the lunar cycle.

If you regularly follow Islamic dates, keeping the current Hijri date visible can make it easier to stay aware of upcoming events and fasting days. Many Muslims today use digital tools such as Hijri calendars, mobile apps, and home screen widgets to track the Islamic calendar more conveniently.

What Does “Hijri” Mean?

The word “Hijri” comes from the Hijrah, the migration of Prophet Muhammad ﷺ from Makkah to Madinah.

This historic event marks the beginning of the Islamic calendar.

For this reason, Islamic years are often written with the abbreviation:

AH (Anno Hegirae)

which means “Year of the Hijrah.”

How Does the Hijri Calendar Work?

The Hijri calendar is based on the moon.

Each month begins with the appearance of a new crescent moon.

Because lunar months are shorter than solar months, the Islamic year contains approximately 354 days.

As a result, Islamic dates move through the Gregorian calendar over time.

This is why Ramadan and other Islamic events occur in different seasons throughout a person’s life.

The 12 Months of the Hijri Calendar

The Islamic calendar contains twelve months:

  1. Muharram
  2. Safar
  3. Rabi al-Awwal
  4. Rabi al-Thani
  5. Jumada al-Awwal
  6. Jumada al-Thani
  7. Rajab
  8. Sha’ban
  9. Ramadan
  10. Shawwal
  11. Dhul Qa’dah
  12. Dhul Hijjah

Each month has its own significance and historical importance within Islamic tradition.

Why Is the Hijri Calendar Important?

The Islamic calendar helps Muslims determine:

  • The beginning of Ramadan
  • Eid al-Fitr
  • Eid al-Adha
  • Hajj season
  • Day of Arafah
  • Day of Ashura
  • Ayyamul Bidh fasting days
  • Islamic New Year

Without the Hijri calendar, it would be difficult to track these important occasions accurately.

Why Does the Hijri Date Sometimes Differ?

You may notice that the Hijri date occasionally differs between countries.

This usually happens because:

  • Moon sightings vary by location
  • Different authorities follow different methods
  • Some communities rely on calculations while others use direct moon observations

A difference of one day is not uncommon in many parts of the world.

This is also why some Muslims prefer Hijri calendars that allow date adjustment to match local moon-sighting announcements.
