: why are some months 31 days or 30 days and why can’t they all be the same.
In: Other
The calendar needs to have a specific amount of days or it will get out of sync with solar time. Someone figured out that having 12 months of which 7 have 31 days, 4 have 30 days and one has 28 or 29 days depending on the year works quite well without getting too much out of sync. It still isn’t perfect, though, and misaligns about 27 seconds every year.
