As I've pointed out before the one thing that is unproblematic to add are more variable date public holidays, right now there is only easter defined,  adding ramadan for example would be no problem. Further expressing a rule is one thing, evaluating it is a something else, and adding some kind of

As I see in the wiki opening hours should be in Gregorian calendar only. But in fact there are many countries and religions using another calendars that affect the opening hours. We (Muslims) used the Hijri Calendar https://en.wikipedia.org/wiki/Islamic_calendar (lunar calendar) for our holi
