Two calendars, and the moon

The Hijri calendar is lunar: a month begins with the new crescent, so it lasts 29 or 30 days and the year runs about eleven days short of the solar one. Turning that into a date on a phone needs a rule, and there are two in common use. Umm al-Qura is computed by Saudi Arabia from the moon’s position over Makkah and published in advance. The tabular calendar ignores the sky altogether and alternates 30- and 29-day months on a fixed thirty-year cycle.

Both are conventions. Many communities still begin Ramadan and the Eids on a sighting of the crescent, which can fall a day after either calculation — the reasons are laid out in why Ramadan starts on different days and why your phone’s Hijri date is wrong. For today’s date and the coming events, see the Islamic calendar.

Questions

Which Hijri calendar does this converter use?
Umm al-Qura, the calendar Saudi Arabia publishes and most apps display, with the tabular (civil) calendar alongside for comparison. Neither is a moon sighting, so a local announcement can differ by a day.
Why do two Hijri converters give different answers for the same date?
Usually because one uses Umm al-Qura and the other the tabular calendar. Over the 612 months from 1421 to 1471 AH they start a month on the same day only 319 times; 258 times the tabular month starts a day later, 12 times two days later, and 23 times a day earlier.
How many days are in a Hijri year?
354 or 355. Each month is 29 or 30 days, and the year is about 11 days shorter than the Gregorian year — which is why Ramadan moves earlier through the seasons, a full cycle every 33 years or so.
What date is 1 Ramadan 1448?
Monday 8 February 2027 in Umm al-Qura. Countries that begin Ramadan on a local sighting may start a day later.
Does the converter work offline or send my dates anywhere?
It uses the calendar data built into your browser, so nothing you enter is sent anywhere.
