Islamic Calendar

The Islamic calendar, also known as the Hijri calendar, is a lunar-based calendar used by Muslims worldwide to determine the dates of Islamic religious events and observances. It began in the year 622 CE, which marks the migration (Hijra) of Prophet Muhammad from Mecca to Medina. The Islamic calendar consists of twelve lunar months and follows a 354 or 355-day year, resulting in it being approximately 10 to 11 days shorter than the Gregorian calendar. The calendar is primarily used for religious purposes, such as determining the dates of Islamic holidays and fasting periods.
