Hey friend !!!!
____________

we know that

=> 1 MIN = 60 sec
=> 1 hour = 60 min
=> 1 day = 24 HRS
=> 1 week = 7 DAYS
=> 1 year = 52 WEEKS

=> 1 year x 52 weeks/year = 52 weeks
=> 52 weeks x 7 days/week = 364 days
=> 364 days x 24 hrs/day = 8736 hrs
=> 8736 hrs x 60 min/hr = 524,160 min
=> 524,160 min x 60 sec/min = 31,449,600 sec

In general we consider a year to be 365 days and a day to be 24 hrs.
Here is what that would look LIKE.
=> 1 year x 365 day/year = 365 days
=> 365 days x 24 hrs/day = 8760 hrs
=> 8760 hrs x 60 min/hr = 525,600 min
=> 525,600 min x 60 sec/min = 31,536,000 sec

hope it will help you..
