Assalamu alaikum/greetings. Inshallah I’m going to be restarting my “moon bits” series. Mostly this is for myself only. If others get benefit out of it too then Alhamdulillah for that. I’ve been doing a lot of thinking though, about the moon sighting issue, as always lol, I mean what’s new? Ever since the whole “28 day ramadan?” controversy, and also ever since the post I saw online by Mohamed Ghilan.
Unfortunately, I’ve been in more “debates” (about moon sighting and other things), then I care to admit. But my main reason for restating this is just for record keeping purposes. I’d kinda like to review this every so often, and try to analyze, to the best of my ability, how often the local, global, pre-calculated and Saudi- (actual) moon sighting calendars converge/differ. Find the below links which will contain the info I’ll be using. Feel free to let me know of any other links that I may have missed which will help in this effort.
