Amun Jadid, also known as the Islamic New Year, is celebrated on the first day of Muharram, marking the beginning of the Islamic lunar calendar. This holiday is observed primarily in the Philippines and is a time for spiritual reflection and community engagement. It commemorates the Hijra, the migration of Prophet Muhammad from Mecca to Medina. Typical customs during Amun Jadid include prayer, personal reflection, and acts of charity. Muslims may also engage in fasting, which symbolizes discipline and restraint. The day is significant for both Shia and Sunni Muslims, with Shia communities mourning the death of Imam Hussein, while Sunnis express gratitude for freedom.
