Islamic (Hijri)
Purely lunar · Umm al-Qura
A purely lunar calendar of 12 months totaling about 354 days, so it slips ~11 days earlier against the seasons each year. It counts from the Hijra, Muhammad’s migration to Medina in 622 CE; shown here in the Umm al-Qura tabular reckoning, which fixes the months by calculation in advance. Traditionally a month opens instead on the first crescent sighted after the new moon, which is why an observed date can fall a day either side of this one. Its days begin at sunset, and the date above turns over at sunset whenever this page knows where you are — falling back to midnight, and saying so, when it does not.
In UTC at 02:02 on October 27, 2026, this calendar read Jumada I 16, 1448 AH (counting the day from midnight). The reading above is live, in your own time zone.
