That's a funny joke. It reminds me of how Sweden actually tried changing to the Gregorian calendar in steps, by skipping leap days for 40 years. Yes, that would make the Swedish calendar to be different from the rest of the world for four decades and the difference to the other world calendars would be changing every four years... It did not go according to plan. But it's the reason February of 1712 in the Swedish calendar did have 30 days. https://en.wikipedia.org/wiki/Swedish_calendar https://en.wikipedia.org/wiki/Swedish_calendar
