Eid Mubarak - with a correct New Crescent Moon


by Salman Hameed

Eid Mubarak to all! 


I wanted to point out that apart from the beautiful calligraphy, the crescent side is accurate here for a waxing Moon (image from here). Waxing crescent is the one that determines the beginning of the new Islamic month, and is visible close to sunset. Here are the phases of the Moon: 



Most flags of Muslim countries, such as Pakistan's or Turkey's, show a waning Moon (visible close to sunrise - not at sunset). Here is a collection of flags of Muslim countries: 

Only Turkmenistan has the waxing crescent (and Mauritania takes an cautious middle path). But of course, while the crescent is right, they placed stars inside the Moon - as if parts of the Moon disappear when they are not lit by the Sun (flags of Malaysia, Algeria, Tunisia, Pakistani and Mauritania do the same). But of course, flags are not meant to be scientifically accurate (stars don't have 5-corners either!), but I thought I'll add some random bit of science to the Eid message.

Here is the Turkmenistan flag - which I think is quite pretty:
