PBNU Announces 1 Muharram 1448 H Falls on Wednesday 17 June, Here's the Reason

The Central Board of Nahdlatul Ulama (PBNU) has announced that 1 Muharram 1448 H falls on Wednesday, 17 June 2026. PBNU made this determination because the new moon (hilal) was not sighted.

According to the official NU website and the official Instagram account of the PBNU Falakiyah Institute on Tuesday (16/6/2026), the announcement was conveyed via letter number 146/PB.08/A.II.11.13/13/06/2026.

In the letter, the PBNU Falakiyah Institute stated that it had conducted rukyatul hilal (moon sighting) on Monday, 29 Zulhijah 1447 H, corresponding to 15 June 2026. All observation points reported that the hilal was not visible.

“As a follow-up, the beginning of the month of Muharram 1448 H coincides with Wednesday Kliwon, 17 June 2026 AD (starting Wednesday evening) on the basis of istikmal,” the letter stated.

The PBNU Falakiyah Institute also urged NU administrators across all regions to actively disseminate this information. Additionally, PBNU called on Muslims to pray for blessings in the new year.

For context, the government has set 1 Muharram 1448 H to fall on Tuesday, 16 June 2026, which is marked as a national public holiday. Furthermore, Muhammadiyah has also determined that 1 Muharram 1448 H falls on Tuesday, 16 June 2026, as stated in the Unified Global Hijri Calendar.
