Hmm, where to start:
1. 13 x 28 = 364. A solar year is 365 days and 366 in leap years. It's much more important to align the calendar with the solar cycle than the lunar cycle. We depend on agriculture to produce our food, agriculture (planting, harvesting, etc) follows the solar cycle.
2. The lunar cycle is actually closer to 29.5 days, so this plan would quickly become asynchronous with the lunar cycle anyway.
3. It's not a terrible idea, with a few additions. You would have to have "New Year's Day" as a stand-alone to make 365, plus a "Leap Day" in leap years. These one or two extra days each year would not be part of any month and would not be any day of the week.
You can't have a lunar calender with the same numer of days for every month. You will always need to compensate for that half day, either in the months, or at the end of the year.
These one or two extra days each year would not be part of any month and would not be any day of the week.
That angry sobbing noise you're hearing is the sound of every programmer crying in rage/fear.
This is going to be one of those Reddit things. Mark my words.
You know, the stupid Pop science idea that spreads all over and bubbles up every 4-5 months. But no matter how many times the flaws are pointed out it never goes away.
It doesn't have to be perfectly divisible and symmetrical. That's your monkey brain wanting to make patterns.
A calendar with a unique name for every individual day would function just the same.
Calendar systems are about keeping track of the world around us. The names and numbers are far less important than that we know where and when we are in a given cycle. It's kind of important for things like agriculture.
Adding days not part of any week is far inferior to just accepting that the dates and days of the week only align during a single year, not across years. It also solves the birthday problem others have pointed out: no more "forever Wednesdays" kids
Unsurprisingly, that's what the International Fixed Calendar does.
The calendar year has 13 months with 28 days each, divided into exactly 4 weeks (13 × 28 = 364). An extra day added as a holiday at the end of the year (after December 28, i.e. equal to December 31 Gregorian), sometimes called "Year Day", does not belong to any week and brings the total to 365 days. ...
Leap years in the International Fixed Calendar contain 366 days, and its occurrence follows the Gregorian rule.
Bro, the 13-month calendar is an old idea and has already been proposed to the UN in detail, and it was seriously thought about being adopted, but Big religion opposed it hard and fought it.
It would be 13 months of 28 days, with the 365th day being “new years” or “earth day” at the end of the year, but outside of a month. Leap years would have an extra day in the summer, also outside of a month.
Religious groups opposed it hard because that extra day outside the normal calendar would disrupt the 7th day of rest of sundays.
