Gregorian Hijri Year Converter

Please insert the year (Hijra or Gregorian) as known, then click the button for the conversion required will appear.






The result is an approximate date. Every Hijri year corresponds to one Gregorian year and vice versa. The conversion is based on the follwing formulae: G=H-(H/33)+622 and H=G-622+(G-622)/32 (Carl Brockelmann: Arabische Grammatik, 12. neubearbeitete Auflage, Leipzig: Harrassowitz, 1948, p. 209). If you want to convert exact dates including month and day please go to the converter offered by the website Conversion of Islamic and Christian dates by J. Thomann or to the Gregorian-Hijri Dates Converter developed by Waleed Muhanna.
