The number 365.24219858156 edit
The number "365.24219858156" looks impressive out of context, but it's based on a calendar which has 2137 regular years of 365 days and 683 leap years of 366 days in a 2820 year cycle. Omar Khayyam didn't observe the tropical year length to that number of decimal places... AnonMoos (talk) 20:32, 9 September 2023 (UTC)
