So, okay, you got me curious.
As it turns out that Muslims of the Muslim faith who live close to or past the Artic Circle and the Antarctic Circle have a "Fatwa," or a clerical decree, directing to follow the fasting schedule of the closest Muslim nation, or mecca itself.
Also as the daily prayer cycle is heliocentric, during the periods of multiple days of darkness they use a similarly adopted prayer schedule.
In any case this did give me quite a chuckle.
Thank you for making this.
