About the Islamic calendar in 2021
The Gregorian year 2021 overlaps 1442–1443 AH, with 1442 AH accounting for most of it. Every date above is a result of the tabular civil model, which is deterministic, reversible within that model and needs no lookup tables. The lunar Hijri year is roughly eleven days shorter than the Gregorian one, which is why Ramaḍān and the two Eids arrive about eleven days earlier each Gregorian year.
FAQ
When does Ramadan start in 2021?
On the tabular Islamic calendar, Ramadan begins 13 April 2021 (Tuesday; 1 Ramaḍān 1442 AH). The dedicated Ramadan page also includes any period crossing into or out of 2021. The actual first day of fasting depends on the local moon sighting and may differ by about a day.
When is Eid in 2021?
Eid al-Fiṭr (1 Shawwāl) is 13 May 2021 (Thursday; 1 Shawwāl 1442 AH); Eid al-Aḍḥā (10 Dhū al-Ḥijjah) is 20 July 2021 (Tuesday; 10 Dhū al-Ḥijjah 1442 AH) by the tabular calendar. These dates may shift by ±1 day with the moon sighting.
What Hijri year is 2021?
2021 overlaps 1442–1443 AH; most of the Gregorian year lies within 1442 AH, which runs from 20 August 2020 to 9 August 2021. Because the Hijri year is about eleven days shorter, one Gregorian year overlaps two Hijri years.
Are these 2021 Islamic dates exact?
They are deterministic results from the tabular civil model and are useful as planning estimates. Religious observances follow the sighting or official determination of the new moon, however, so confirm the observed day with your local authority.
