The Hijri (Islamic) calendar counts from the Hijra, the Prophet's move from Makkah to Madinah. Year 1 AH began on Friday 16 July 622 in the old Julian calendar, which is 19 July 622 when today's Gregorian calendar is run backwards. Each month is one cycle of the moon, 29 or 30 days, so a Hijri year of 12 months is 354 or 355 days, about 11 days shorter than a Gregorian year. That is why Ramadan moves about 11 days earlier each year.
The formula
days since 1 AH = date − 16 July 622 (Julian)
years gone ≈ days ÷ 354.367 (the average Hijri year)
Tabular calendar: day number of a Hijri date = (year − 1) × 354 + whole part of ((3 + 11 × year) ÷ 30) + 29 × (month − 1) + whole part of (month ÷ 2) + day − 1
Umm al-Qura: look the month up in the official table, then count the days from its first day
Worked example
Take Wednesday 18 February 2026. From 19 July 622 (16 July in the Julian calendar) to 18 February 2026 is 512,650 days. 512,650 ÷ 354.367 = 1,446.66, so 1,446 Hijri years have gone and we are in year 1447. In the tabular (civil) calendar, 1 Ramadan 1447 is day (1,446 × 354) + 530 + (29 × 8) + 4 + 1 − 1 = 511,884 + 530 + 232 + 4 = 512,650, where 530 is the whole part of (3 + 11 × 1447) ÷ 30 = 15,920 ÷ 30 = 530.67. That is the same day, so 18 February 2026 is 1 Ramadan 1447 AH. The Umm al-Qura table agrees: Muharram to Shaban 1447 have 30 + 29 + 30 + 30 + 30 + 29 + 30 + 29 = 237 days from 26 June 2025, so 18 February 2026 is day 238 of the year, the first day of Ramadan. The astronomical tabular calendar starts a day earlier and says 2 Ramadan.
The three calendars
| Calendar | How months are set | Used by |
|---|---|---|
| Umm al-Qura | Worked out in advance from the new moon over Makkah; published by Saudi Arabia | Saudi government and business dates, many apps |
| Tabular, civil epoch | Fixed rule: 30 and 29 day months in turn, 11 leap years in 30, starting Friday 16 July 622 | Kuwaiti algorithm, many computer systems |
| Tabular, astronomical epoch | Same rule, starting Thursday 15 July 622, so a day ahead | Some historians and software |
In the tabular calendar years 2, 5, 7, 10, 13, 16, 18, 21, 24, 26 and 29 of every 30-year cycle are leap years, with 30 days in Dhu al-Hijjah instead of 29. 1447 AH is year 7 of its cycle (1447 = 30 × 48 + 7), so it has 355 days.

Moon sighting and your local date
Umm al-Qura and the tabular calendars are calculated, but many countries start Ramadan, Eid and every month only when the new crescent is seen. That can make the local date a day later than the calculated one, and sometimes a day earlier. The days to Ramadan and Eid are therefore estimates. In Advanced you can shift every Hijri date by one or two days to match your country.
Umm al-Qura dates for 1343 to 1500 AH (1 August 1924 to 16 November 2077) come from the published Umm al-Qura month table, checked against the hijridate library and your browser's own Umm al-Qura calendar on 13 October 2026. Dates outside that range use your browser's calendar. Gregorian dates before 15 October 1582 are in the proleptic Gregorian calendar.
Common questions
What is today's Hijri date?
The converter opens on today's date and shows it in the Hijri calendar, in English and Arabic, with the weekday. It uses the Umm al-Qura calendar of Saudi Arabia unless you choose a tabular calendar. Your country may be a day different if it starts months by moon sighting.
What is 18 February 2026 in the Hijri calendar?
Wednesday 18 February 2026 is 1 Ramadan 1447 AH in the Umm al-Qura calendar and in the tabular civil calendar. The tabular astronomical calendar, which starts a day earlier, gives 2 Ramadan 1447.
What is the difference between Umm al-Qura and the tabular Islamic calendar?
Umm al-Qura is the official calendar of Saudi Arabia. Its months are set in advance from where the new moon is over Makkah, so 29 and 30 day months fall unevenly. The tabular calendar uses a fixed rule instead: months alternate 30 and 29 days, and 11 years in every 30 get an extra day. The two usually agree, or differ by a day.
When is Ramadan 2027?
By the Umm al-Qura calendar, 1 Ramadan 1448 falls on Monday 8 February 2027 and Eid al-Fitr on Tuesday 9 March 2027. These are estimates: many countries start Ramadan and Eid when the new crescent moon is seen, so the actual dates can be a day later or earlier where you live.
How old am I in Hijri years?
A Hijri year is about 354 days, 11 days shorter than a Gregorian year, so your Hijri age is a little higher. Someone born on 15 May 1990 (20 Shawwal 1410) is 37 Hijri years, 6 months and 12 days old on 13 October 2026, but 36 in Gregorian years.
Why might my local Hijri date be a day different?
Many countries, including Pakistan, India, Bangladesh, Morocco and the UK's moon sighting groups, start each month when the crescent is actually seen, which can be a day after the calculated date. Use the day shift in Advanced to move every result by one or two days to match your local calendar.
