About this calendar

Islamic months are lunar: each one begins with the new crescent, so a month is 29 or 30 days and a year is 354 or 355. The ranges above are calculated — the months as actually observed in any given country can shift by a day. For the holy months, always check your local moon-sighting announcement.

How many days are in Hijri year 1447?

Hijri year 1447 has 355 days on the Umm al-Qura calendar and 355 on the tabular calendar. Lunar years run about 11 days shorter than solar years, which is why Islamic months drift earlier through the seasons.

The tabular calendar follows fixed arithmetic; Umm al-Qura follows predicted moon visibility over Mecca. They agree on most months and differ by a day on some — the same reason two countries can start Ramadan on different days.
