That’s right. Apparently, there’s an algorithm called “The Kuwaiti Algorithm”. I assure you, it’s not as retarded as you think at all!
When I first read the title I was like “What the!?” and I thought of it as an awful joke since it’s in Wikipedia. But turns out to be a real and interesting thing actually.
It’s some sort of algorithm that converts Hijri to Gregorian calendars. Noting that Hijri is lunar-based and Gregorian is solar-based, Hijri is hard to precisely calculate because it depends on the moon’s vision and that is usually declared by religious authorities (Ramadan and Adhha perhaps?).
So someone used a large statistical amount of Hijri dates in Kuwait and came up with this algorithm. Might be a couple of days off the real calendar, but that’s an awesome job actually!
