    Seconds Per Year

    The first answer is 60 x 60 x 24 x 365 since a year is commonly defined to have 365 days, each with 24 hours, each with 60 minutes, each with 60 seconds. Using these definitions the number of seconds is 31,536,000 exactly.

    But a year can also be defined as the orbital rotation period of the Earth around the Sun. The most accurate measurement of this time [wikipedia] is 365.256366 days, so the number of seconds is:

    365.256366 x 24 x 60 x 60 = 31,558,150.02

    using this definition

    1 day =24 hrs

    1 hr =60 mins

    1 min =60 sec

    1 month =30 days

    1 year =12 months

    l

    60per min times 60 per hour=3600 per hour

    3600 per hour times 24 hours per day =86400

    86400 per day times 365 days per year = 31, 556 ,926 seconds per year

    this of course changes with the leap year
