A lunar calendar
The Hijri calendar follows lunar cycles and its year is shorter than the Gregorian year. Ramadan, Hajj and other Islamic occasions therefore move earlier through the Gregorian calendar each year.
See important dates ahead
Knowing significant dates in advance helps you prepare fasting, worship and family plans calmly. Enable reminders only for the occasions that are meaningful to your routine.
Remember local observation differences
The start of a lunar month may differ by one day between regions due to calculation or local moon sighting. For major acts of worship, follow the announcement of the appropriate local religious authority.
