Muharram, the first month of the Islamic lunar calendar and one of Islam’s four sacred months, begins as Muslims worldwide enter a period marked by grief, remembrance, and prayer rather than celebration. Sources say Muharram in 2026 starts around mid-June, with reporting indicating June 16 for the start of the Islamic New Year 1448 AH, and June 17 for the first night of mourning ceremonies in Tehran. In Iran’s capital, thousands attend gatherings for the opening nights of Muharram, including congregations at mosques, religious centers, and community spaces. Ceremonies include recitations of elegies, sermons focused on the events of Karbala, and prayers dedicated to Imam Hussain and his companions. Sources describe black banners and mourning flags displayed in public areas, and attendees using traditional symbols associated with the occasion. The month is closely linked to Shia commemorations of Imam Hussain’s martyrdom at the Battle of Karbala in 680 CE, which is observed on the 10th day of Muharram as Ashura. Sources also note that Sunni observances of Ashura differ, including fasting and remembrance of the Prophet Moses narrative. Additional reports reference observances at major shrines in cities such as Mashhad and Qom.
