Convert dates between the Islamic Hijri calendar and the Gregorian calendar, and find when Ramadan starts.
About the Hijri Date Converter
The Hijri calendar is lunar: 12 months of 29 or 30 days, about 354 days a year, so Ramadan moves about 11 days earlier each Gregorian year. Year 1 AH began in 622 CE with the Prophet's migration to Medina.
This converter uses the Umm al-Qura calendar, Saudi Arabia's official calendar, as built into modern browsers (valid 1937–2076). Many communities start Ramadan and the Eids on a local moon sighting, which can be a day later.
The formula
1 Hijri year ≈ 354.37 days; 1 lunar month ≈ 29.53 days
Upcoming Ramadan dates (Umm al-Qura)
