[Tagging] Opening hours syntax for non Gregorian calendar

[Saeed Hubaishan]

Adding ramadan as <variable_date> is good.

I also  suggest adding optional [@calendar] to date range rules for non Gregorian dates and using month number instead of month abber name for example:

Sa-Th 09:00-21:00; 09/01-09/30 @hijri 20:00-03:00

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 "context" value to help in the later (for example a time zone value as has been suggested previously)  could potentially work.

That doesn't seems to solve the problem that would occur. For instance, how to represent the first Sunday (a feature in Gregorian calendar) after Chinese traditional ceremony X (a feature in Chinese traditional calendar) in the opening time syntax, if they're split up for "simplicity"? What about when the opening time also cover non-holiday festivals that only occurs according to either calendars?

Problem of splitting: what if a mapper gives the opening times in both calendar_X and calendar_Y
and they disagree?  Consumers will have to have rules like: in country_Z use calendar_X if given,
otherwise use standard opening_hours if given, otherwise use calendar_Y if given, otherwise
pick at random from what is left.
