What Is an Islamic (Hijri) Date?
An Islamic or Hijri date is the date format used in the Islamic lunar calendar. It begins from the Hijrah — the migration of Prophet Muhammad ﷺ from Makkah to Madinah — which marks the start of the Islamic year.
How the Hijri Calendar Works
The Hijri calendar is based on the moon. Each month begins when the new crescent moon is sighted, which makes the Islamic year 10–11 days shorter than the solar year.
Lunar Month Explanation
A lunar month has 29 or 30 days, depending on the moon’s cycle. Each Islamic month begins when the thin new crescent moon is seen in the sky.
