Yom Ashura or Ashura, and in Guyana, Jamaica, Trinidad and Tobago, and Suriname as 'Hussay' or Hosay, is the tenth day of Muharram in the Islamic calendar. In Sunni Islam, Ashura also marks the day that Moses and the Israelites were saved from Pharaoh by God creating a path in the Sea, and is the Islamic equivalent to Yom Kippur. Other commemorations include Noah leaving the Ark and Muhammad's arrival in Medina.For the majority of Shi'a Muslims, Ashura marks the climax of the Remembrance of Muharram, and commemorates the death of Husayn ibn Ali, the grandson of Muhammad at the Battle of Karbala on 10 Muharram in the year 61 AH (around October 10, 680 CE).
