From Muharram 1, 1440 (September 11, 2018) to Dhul Hijjah 1, 1467 (October 12, 2045)
The Islamic calendar adopted by Fiqh Council of North America (FCNA) is based on calculations with Ittihadul-Mataali’ concept for the sake of global unity. FCNA decided to follow The European Council for Fatwa and Research (ECFR), which states that the sighting is not a requirement but just the means of ascertaining the beginning for a new month, and that is now attained by exact calculations.
The criteria are that after conjunction somewhere on the globe, at local sunset, the angle between sun and moon should be at least 8° and moon should be at least 5° above horizon. If these conditions are met, the month starts the next day, otherwise the month starts on the day following next day.
Note: Eidul Adha will be following Yaum ‘Arafah as determined by the Supreme Court of Saudi Arabia.
