Don't Forget Tasu'a and Ashura Fasts: Here's the Schedule According to the Government, Muhammadiyah and PBNU

Muslims are reminded not to miss the sunnah fasts of Tasu’a and Ashura in the month of Muharram 1448 Hijri. The fasts, observed on the 9th and 10th of Muharram, hold great virtue, with the Prophet Muhammad (peace be upon him) stating that the Ashura fast can expiate the sins of the previous year. Muharram itself is one of the sacred months in Islam and part of the four forbidden months (asyhurul hurum), during which Muslims are encouraged to increase their acts of worship, including fasting. According to the government’s determination through the Ministry of Religious Affairs, 1 Muharram 1448 H falls on Tuesday, 16 June 2026. Consequently, the Tasu’a fast (9 Muharram) will be observed on Wednesday, 24 June 2026, and the Ashura fast (10 Muharram) on Thursday, 25 June 2026. This government decision aligns with the Global Hijri Calendar (KHGT) guidelines compiled by the Tarjih and Tajdid Council of Muhammadiyah. Meanwhile, the Falakiyah Institute of the Nahdlatul Ulama Executive Board (LF PBNU) has set 1 Muharram 1448 H on Wednesday, 17 June 2026, based on rukyatul hilal (moon sighting). Under this determination, the Tasu’a fast falls on Thursday, 25 June 2026, and the Ashura fast on Friday, 26 June 2026. The difference arises from the varying methods used to determine the start of Muharram. The public is advised to follow the decision they believe in and to avoid debating the differences.
