Muharram

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 Battle of Karbala (680 CE) was a confrontation in which Husayn ibn Ali, grandson of Prophet Muhammad, was killed with his companions by Umayyad forces near the Euphrates. It became one of the most consequential events in Islamic history, shaping the development of Shia Islam.

The Islamic calendar, or Hijri calendar, is a lunar calendar of 12 months beginning with Prophet Muhammad's migration to Medina in 622 CE. It governs Islamic religious observances, festivals, and historical dating throughout the Muslim world.
