How many years is the cycle of the lunar calendar and the Gregorian calendar? For example, I have a 20 13 calendar. Except the year. How long will it take?

The solar calendar is different from the lunar calendar. Our lunar calendar, also known as the Old Yellow Calendar, is based on the combination of ten days and twelve earthly branches, with a cycle of sixty years, also known as "one Jia Zi". The Gregorian calendar is different. The accumulation and accumulation of numbers will not cycle. If reincarnation is necessary, it will be another civilization after the destruction of our mankind.
