Indonesian Islamic Council Sets New Year One Day Later Than Government

The Indonesian Nahdlatul Ulama Scholars Council (PBNU) has officially declared the start of the Islamic New Year 1448 Hijriah to be on Wednesday, June 17, 2026. This decision, formalized by the PBNU's Falakiyah Institution, deviates from the Indonesian government's official calendar, which designates Tuesday, June 16, 2026, as the first day of Muharram.

The PBNU's determination was made after its moon-sighting teams across Indonesia were unable to observe the new crescent moon on Monday, June 15, 2026. According to the official announcement, all reporting locations confirmed the hilal was not visible. Consequently, PBNU followed the 'istikmal' method, completing the month of Dzulhijjah to 30 days, thus shifting the start of Muharram to June 17.

The Falakiyah Institution expressed gratitude to all members who participated in the moon-sighting efforts. It also urged regional PBNU branches to disseminate the new date to the wider Nahdlatul Ulama community and the public. The differing dates highlight the ongoing practice of relying on direct astronomical observation versus governmental decree for religious calendar determinations in Indonesia.
