Note that the calendar dates for the months of Ramaḍān, Shawwāl and Dhū ’l-Ḥijja are often adjusted
by the religious authorities of Saudi Arabia after reported sightings of the lunar crescent
(see Advancement and Postponement of the Umm al-Qura Calendar)

Dates for the years 1356 AH to 1411 AH are based on a calendar conversion table published in the
early 1990s by the King Fahd University of Petroleum & Minerals Research Institute (Dhahran)

When the webpage is loaded the calendar converter will output the date and the length of the current month in the Umm al-Qura calendar. The date can be set manually to any other date between the limits given above.
