Muhammadiyah Continues Dialogues for Uniform Islamic Calendar System
Muhammadiyah general chairman Haedar Nashir stated that his organisation is continuing a series of dialogues to standardise the determination of Islamic worship times through the Global Single Hijriah Calendar (KHGT).
“The concrete step is that we will continue to engage in dialogues with organisations at the national level and continue the dialogues that have already been initiated at the international level,” Haedar said after performing Idulfitri prayers for 1447 H at UMY in Bantul, DIY, on Friday morning (20/3).
According to Haedar, the Muhammadiyah Central Executive’s Tarjih Team has been working for a year to discuss the implementation of the KHGT, which is based on the 2016 Turkish Criteria.
“I am confident that in the future, these dialogues will continue to open up, and our principle, wherever it comes from, is that we have one calendar, where one day has the same date, differing only in time, just like our Friday prayers. One Friday the same, the same date, but different times across the Islamic world,” Haedar said.
Haedar also believes that with the realisation of symbolic unity among Muslims globally through a single calendar system based on hisab, differences such as the determination of Idulfitri 1447 H can be avoided.
“Thanks be to God in the future, whenever it may be, the entire Islamic world should not continue to differ and have a Single Global Calendar,” Haedar hoped.
“I am confident that in the future, insyaallah, these differences will be minimised, but of course, this requires open heart-to-heart dialogues and clear minds with the highest level of knowledge,” he said.
Unlike the government, the Muhammadiyah Central Executive determined that 1 Syawal or Idulfitri 1447 Hijriah falls on Friday, 20 March 2026. This determination is contained in the Central Leadership Statement of Muhammadiyah Number 2/MLM/1.0/E/2025 on the Determination of the Results of Hisab for Ramadan, Syawal, and Zulhijah 1447 H.
The determination of the Lebaran date was made by the Muhammadiyah Central Executive based on the hakiki hisab method for the existence of the crescent and the Global Single Hijriah Calendar (KHGT), which ensures that the start of a new month does not depend on the physical visibility of the crescent, differing from the government’s potential method.
The determination of 1 Syawal is based on the results of hakiki hisab for the existence of the crescent, guided by the Majelis Tarjih and Tajdid of the Muhammadiyah Central Executive. This is then included in the Muhammadiyah Central Executive Statement Number 2/MLM/1.0/E/2025, which was released in Yogyakarta on 22 September 2025.
Meanwhile, the Indonesian Government set Hari Raya Idulfitri 1447 Hijriah or Lebaran 2026 to fall on Saturday, 21 March, based on the results of the isbat session held by the Ministry of Religious Affairs on Thursday (19/3).
