Islamic Calendar

Ashura is the tenth day of Muharram, the first month of the Islamic calendar. Sacred for its connection to Prophet Musa's deliverance and transformed by the martyrdom of Imam Husayn at Karbala in 680 CE, it is observed across all Islamic traditions.

The Hijra (622 CE) was Prophet Muhammad's migration from Mecca to Medina, marking the Islamic calendar's beginning and establishing the first Islamic state. This pivotal event transformed Islam from a persecuted movement into a thriving autonomous community.

The Hijri calendar is a lunar calendar of twelve months, four of them sacred, instituted as an era by the caliph Umar ibn al-Khattab and counted from the Hijra of 622 CE. It governs Islamic worship, festivals, and historical dating.
