How to use it and understand the result
Choose a Gregorian date or enter a Hijri year, month and day for the reverse conversion. Months: 1 Muharram, 2 Safar, 3 Rabi al-Awwal, 4 Rabi al-Thani, 5 Jumada al-Ula, 6 Jumada al-Thani, 7 Rajab, 8 Shaban, 9 Ramadan, 10 Shawwal, 11 Dhu al-Qadah, 12 Dhu al-Hijjah.
Conversion uses the same Umm al-Qura calculation as this site’s calendar and Ramadan timetable. Gregorian input supports 1938–2076, while Hijri input supports 1356–1500. A request for day 30 in a 29-day month produces an error rather than a silently changed date.
The result labels a civil calendar day; it does not measure whether sunset has occurred at your location. Moon sighting and official local announcements may differ. Check your country’s responsible authority for Ramadan and Eid dates.
