Differences in determining the beginning of the lunar month in Indonesia often spark public discourse due to the dichotomy between hisab and rukyat methods. The emergence of the Single Global Hijri Calendar (KHGT) concept offers a solution for international unification of the Islamic calendar. This article aims to examine the parameters of the KHGT and their relevance to the development of rukyatul hilal practices in Indonesia. The research method used is qualitative, with a library research approach and descriptive-comparative analysis of astronomical data and the policies of religious authorities in Indonesia. The hypothesis of this study asserts that the KHGT does not eliminate the essence of rukyat, but rather repositions rukyat as a verification instrument for precise mathematical calculations. Adopting the KHGT parameters in Indonesia requires synergy between the readiness of digital optical technology and the political will of Islamic community organizations to achieve certainty of uniform and collective worship laws.
