According to the perspectives of the Hanafi, Maliki, and Hanbali Jurists, the timing disparities around the world do not impact the sighting of the moon, except in cases where excessive distance results in a time variance exceeding 12 hours. Consequently, this discrepancy may lead to a divergence between the dates of observation during day and night. Hence, in regions spanning Asia, Europe, Africa, and America, the sighting of the crescent by any recognized observatory will be deemed valid.

In the United Kingdom, adherence is to the British observatory, which applies a six-tier visibility classification system denoted by letters A through F. Tiers A to C typically signify the commencement of a new Islamic month on the subsequent day. The UK and Europe Hilal Forum, guided by these observatory assessments, will proactively announce the dates of crescent sightings, ensuring that precise announcements are issued a year in advance. Furthermore, it is reiterated that the representatives of the UK and Europe Hilal Forum will consistently announce the advent of new lunar months and sighting of the Hilal each month.
