63,072,000 seconds is about two years.
1,451,618,596 seconds in 46 years.
43 years = 1.35694782 × 109 seconds.
There are 432339120000000000 seconds in 13.7 billion years.
Depending on the number of leap years in the period (14 or 15), there will be 1893369600 or 1893456000 seconds - plus any leap seconds which may be added.
Without accounting for leap years and such, we have 60 x 365 x 24 x 60 x 60 = 1892160000 seconds
2 years = 63,113,851.9 seconds.around 63072000
63072000 seconds for a regular year, but 63244800 seconds in a leap year.
Assuming that neither of the years is a leap year, the number of seconds in one year is (365 x 24 x 60 x 60) = 31536000 seconds, therefore, the number of seconds in two years would be 31536000 x 2 = 63072000 seconds.If one of the years is a leap year, the number of seconds is equal to (365 x 24 x 60 x 60) + (366 x 24 x 60 x 60) = 63158400 seconds.
