Number of seconds in a year
Let us calculate How many seconds are in a 24 hour day
We know that
1 minute 60 seconds
1 hour =60 minutes
1 day=24 hours
1 year = 365 days
Hence the number of seconds in year =
=3600 X 365 x 24 x 60 x 60
=31, 536, 000 seconds
Hence there are 31, 536, 000 seconds in a year
