List of Islamic years

This is a list of years in the Hijri era (Latin: anno Hegirae or AH) with the corresponding common era (CE) years where applicable. Years in this list are lunar years since the Hijrah, counted according to the lunar Hijri calendar (known in the West as "the Islamic calendar"). For Hijri years since 1297 AH (1879/1881 CE), the Gregorian date of 1 Muharram, the first day of the year is given.

The first Hijri year (AH 1, the epoch of the era) was retrospectively considered to have begun on the Julian calendar date 15 July 622 CE, denoted as "1 Muharram, AH 1". Years prior to this are reckoned in English as BH ("Before the Hijra").

In principle, each month in the lunar Hijri calendar begins with sighting of the new crescent moon (after a New Moon) at sunset. Because of this, the calendar is dependent on observational conditions and cannot be predicted or reconstructed with certainty. The tabular Islamic calendar, which determines the dates algorithmically, is used directly in some traditions and as an estimation in many computer systems. Because of this, dates may vary by up to two days between traditions or countries.
