The Hijri calendar (also known as the Islamic calendar) is a lunar calendar used by Muslims worldwide for religious observances. Unlike the Gregorian calendar, which follows the sun's cycle, the Hijri calendar is based on the phases of the moon. Each of its 12 months begins with the sighting of the new crescent moon (Hilal), making it approximately 11 days shorter than the Gregorian year.
The calendar begins with the Hijrah — the migration of Prophet Muhammad (PBUH) from Makkah to Madinah in 622 CE. This event marks the founding of the first Muslim community and is designated as Year 1 (1 AH) in the Islamic era. The current year in the Hijri calendar is 1447 AH.

The Hijri calendar's 12 months each have between 29 and 30 days, with a total year length of 354 or 355 days. This causes Islamic holidays like Ramadan and Eid to shift approximately 11 days earlier each Gregorian year, cycling through all seasons over a 33-year period.
