The End of an Era: Muhammadiyah‘s Transition from Hisab Hakiki to KHGT
On March 31, 2025, the Islamic organization Muhammadiyah will implement a significant transition in determining the start of the Islamic months. The institution will be shifting from the traditional Hisab Hakiki method to the Kalender Hijriah Global Tunggal (KHGT). This move aims to bring unity in timekeeping within the global Muslim community.
Understanding the Transition
The Hisab Hakiki method, which Muhammadiyah has adhered to for decades, bases its determination on the physical observation of the moon, known as “wujudul hilal.” Several criteria, such as the moon’s rise before sunset and the positioning of its disk, must be met for a month to begin. However, on March 29, 2025, the moon did not meet these criteria in Indonesia, cementing the use of Hisab Hakiki.
“This shift represents an evolution in Islamic timekeeping, responding to modern pluralistic societies,” says Dr. Ahmad, a leading researcher in Islamic calendar systems.
The Advantages of the Global Islamic Calendar
The KHGT offers a synchronized approach where the Islamic calendar is globally unified. This system acknowledges Earth as a single cohesive geographical and cultural entity, allowing for the simultaneous commencement of Islamic months worldwide.
Did you know? Unification of the Islamic calendar could enhance global coordination among Muslim communities, particularly for Ramadan and Hajj planning.
Global Unity and Modern Challenges
As technology and globalization forge deeper connections, religious communities grapple with maintaining traditional practices in a rapidly changing world. Muhammadiyah’s adoption of KHGT reflects a broader trend toward global unity and adaptability.
Pro tip: Exploring unified global systems like KHGT can offer lessons in addressing complex socio-religious challenges of modernity.
In a study published by the International Journal of Islamic Studies, researchers found that synchronized religious calendars could enhance cross-border community collaboration, enriching religious, cultural, and educational exchanges.
Case Studies: The Impact on Muslim Communities
In Indonesia, one of the world’s largest Muslim-majority nations, local communities often face discrepancies with regions using different calendar systems. Transitioning to KHGT could mitigate these challenges by providing a single reference point, streamlining religious observances.
The city of Jakarta, for instance, could benefit from consistent zakat and fasting timetable, promoting community welfare and spiritual harmony.
