If we did that now, the politicians will call those tax-free days, with
the remainder being taxed at 100%.

Something like the 0 and 00 on American Roulette wheels?

Keep in mind that the 'modern' calendar was the creation of a religious institution to keep the calendar from 'slipping' and entirely for religious purposes. Islam uses a lunar calendar and slips by about 10 days each year. This is most significant during Ramadan, when fasting is from sunrise to sunset. Makes things a bit hard the further north (or south) one goes when Ramadan falls in the local summer time. But, several other groups, including Buddhists and others use calendars apart from the Gregorian calendar - no surprise there at all.
