There are 60 seconds in a minute, and 60 minutes in an hour, so there are 60^2 = 3600s in an hour. There are 24 hours in a day, so there are 3600*24 = 86,400 seconds in a day. There are 365 days in a normal year, so there are 86,400*365 = 31,536,000 seconds in a year. There are 366 days in a leap year, so there are 31,622,400 seconds in a leap year. Scientifically seen, there are c. 365.25 days in a year, so in an actual year (scientifically seen) there are 31,557,600 seconds in a year.
