How to detect Russian holidays and weekends in python? Are there any ready-made solutions?

Answer 1

Parse some resource with a production calendar, and write a check method, something like this:

YEAR_HOLIDAYS = 'HOLIDAYS:{year}' 

   ...
    @classmethod
    def is_work_day(cls, date):
        if date.weekday() in [5,6]:
            return False
        holidays = cache.get(YEAR_HOLIDAYS.format(year=date.year))
        if not holidays:
            holidays = cls.objects.filter(year=date.year).values_list('date', flat=True)
            cache.set(YEAR_HOLIDAYS.format(year=date.year), holidays)
        if date in holidays:
            return False
        return True

Add the logic of transferring working days here - and in production..
