Base data: time. 1 year (normal year) = 365 days = 31,536,000 sec. 1 year (leap year) = 365 days = 31,622,400 sec.
THAT person from the Roman Empire period created the leap year
The number of days in a year is actually 365.24 and not 365. A leap year was therefore established to overcome this discrepancy. It was Julius Caesar who decided this. However, even with the establishment of a leap year, there are still discrepancies, so it is omitted three times every 400 years. This was decided by Pope Gregory XIII.
