How many seconds are in 130000 years?

Answer 1

Since the Georgian Calender repeats itself over 400 years, and the rules to the Georgian calender state that there is a leap year once every 4 years, but not one that is divisible by 100 unless also divisible by 400, there is 146,097 days every 400 years. There are exactly 325 cycles of 400 years in 130000 years, so we have 47,481,525 days. Each day is 86,400 seconds long, so multiplying the previous two figures give 4,102,403,760,000 seconds.

Remember this figure is before taking into account of leap seconds.
