Hijri Calendar
The Islamic calendar is lunar, and knowing how it works protects you from confusion about dates. These guides explain why the Hijri calendar is what it is, how the twelve months work, and — most importantly — why a calculated date is an estimate that must be confirmed by moon sighting. This platform always labels calculated dates as estimates and distinguishes them from official announcements.
