Wrong approach. If you want government backed holidays, just create list of dates and everyone can choose compatible with his needs (Religion, etc) so jews can have their Hanukkah, christians christmas, atheist can have solstice (like i prefer) or whataver they want.
⚡️🇺🇦 NEW - Zelensky: The dates of holidays in Ukraine will be changed. There are bad coincidences; some dates came from the Soviet Union. True Christmas has been returned to the 25th, and the same should be done with other dates.

They're not allowed to have elections, never mind choose holidays.
