Understanding the Hijri (Islamic) Calendar
The Hijri calendar (التقويم الهجري) is a purely lunar calendar consisting of 12 synodic lunar months in a year of 354 or 355 days. It is used across the Islamic world to determine the correct days of Islamic holidays, Ramadan fasting, Hajj pilgrimage, and religious observances.
The calendar began in 622 CE, marking the Hijrah — the emigration of Prophet Muhammad (PBUH) from Mecca to Medina. Dates in the Hijri calendar are designated with AH (Latin: Anno Hegirae, "In the year of the Hijrah").
Sunset Rule (Maghrib)
In Islamic tradition, a new day begins at sunset (Maghrib), not at midnight. If an event occurs after sunset on a Tuesday evening, its Hijri date belongs to Wednesday. Tick the "After Sunset / Maghrib" box to convert evening dates accurately.
12 Lunar Months
A Hijri year is 10 to 12 days shorter than a Gregorian solar year. This is why Islamic months like Ramadan cycle backwards through all four seasons over a 33-year cycle.
