The Concept of the Single Global Hijri Calendar (KHGT) from the Perspective of the Lembaga Falakiyah of Nahdlatul Ulama Executive Board (LF PBNU)

Abstract

The establishment of a single global Hijri calendar is a topic of debate among international scholars and astronomers. A single global Hijri calendar is an attempt to create uniformity in the Islamic calendar throughout the world. However, this initiative has drawn criticism, especially from the Nahdhatul Ulama Executive Board, the central level organization that leads Nahdlatul Ulama (NU), one of the largest Islamic religious organizations in Indonesia. This article aims to examine the views of the LF PBNU the concept of a single global Hijri calendar, as well as understand the scientific basis for LF PBNU's criticism of the principles used in a single global Hijri calendar. This research method uses qualitative analysis through literature studies, documents or seminar materials presented by representatives of Lajnah Falakiyah PBNU. The research results show that the LF PBNU's main objection to a single global Hijri calendar lies in the differences in the hisab and rukyat methods used, as well as in the limitations of applying this calendar in the local Indonesian context. By understanding the concept of KHGT according to LF PBNU, this article contributes to academic discussions about efforts to harmonize the Islamic calendar to accommodate the plurality of views in the Islamic world.
