The KRM Coordination Council and German Islamic Federations
The Koordinationsrat der Muslime (KRM) coordinates Germany's major Islamic umbrella bodies: DITIB (Turkish-Islamic Union), IGMG (Milli Görüş), ZMD (Central Council of Muslims), and VIKZ (Association of Islamic Cultural Centers). Together, they issue coordinated statements on Ramadan and Eid declarations, ensuring consistency for schools, employers, and public authorities.
Hilal Visibility Criteria and Astronomical Standards
Germany follows the Istanbul International Accord (1978/2016) as an astronomical standard: when the crescent moon becomes visible anywhere on Earth after conjunction — meeting minimum altitude and elongation thresholds — the new Islamic month begins. The Turkish Diyanet's precise ephemeris calculations are the primary reference for most German mosques.
Civil Day and Maghrib Religious Transition
For daily Islamic observances such as Iftar and Eid prayers, sunset (Maghrib time) is the governing moment. This platform updates the civil date at 12:00 AM midnight CET (Europe/Berlin). Germany spans a single time zone, making national calendar standardization straightforward.
