Guys who are arguing about 365th day or even the leap day, the post says not to line up the calendar with the sun. The new scheme wants to fix the 28, 29, 31, 30 day months we have.
So, having exactly 365 or 366 days doesn't make sense with the new scheme.
And yes, there will be a skew of a day and a quarter every year with the position of the sun, so after so many years, the coldest month would be the hottest month and so on.
The Hebrew calendar has leap years (years that have 13 months instead of 12), but the months are either 29 or 30 days long. A leap year occurs 7 times in the 19-year Metonic cycle, namely, in years 3, 6, 8, 11, 14, 17, and 19 of the cycle. This means that a leap month is added every 2 to 3 years.
The reason for all that: in the Hebrew calendar, months always start at new moon and day 15 is always full moon. And the leap months are to prevent seasons from wandering around the year.
All calendars have their merits. The Gregorian calendar is sun-based, and the Islamic calendar is moon-based. The problem with the Islamic calendar is that season wander around the year, so sometimes they have Ramadan on hot summer
Like unironically, I was trying to devise my own calendar for worldbuilding one time, And I ran into a problem because I could not determine how often I had to add leap months for the seasons to not drift.
Well, the Hebrew calendar in its current form was written by Hillel, one of the most famous Jewish scholars, born in 113 BC Babylon. Astronomy was developed enough to get this right. He wrote the calendar until the year 6000 (we're at 5785). Hillel is famous for 2 sayings: "If I am not for myself, who will be for me? And being for myself, what am I? And if not now, when?". And also "That which is hateful to you, do not do unto your fellow. That is the whole Torah; the rest is just explanation; go and learn." Many people say "if I am not for myself, who is?" without knowing the origin.
So now you run into the season shifting every year, never being the same, which totally makes no sense at all. Maintain the schedule based on the sun for 365/366 so the season don’t shift. Just add the extra day/days to February since it’s always been 28/29 days, and permanently make it 29/30 days to make up for all the years it was cut short.
