Umm al-Qura and moon sighting

Umm al-Qura is a calculated calendar used for official business in Saudi Arabia. Religious occasions such as the start of Ramadan, Eid al-Fitr and Eid al-Adha are confirmed by sighting the new moon, so they can fall a day earlier or later than the calculated date. Some countries also use their own calculations.

Months with 29 or 30 days

Hijri months have 29 or 30 days, depending on the moon. If you type the 30th of a month that has only 29 days that year, the converter tells you instead of guessing.
