1 hour = 60 mins
1 min = 60 seconds
Hence 1 hour = 60 x 60 = 3600 seconds
1 day = 24 hours
Hence 1 day = 24 hours = 24 x 3600 seconds = 86400 seconds
If the year is not a leap year then number of days in that year will be 365 days.
Therefore 365 days = 365 x 24 x 3600 = 31536000 seconds.
If the year is a leap year then number of days in that year will be 366 days.
Therefore 366 days = 366 x 24 x 3600 = 31622400 seconds.
as we know that, 1 year = 365 days
1 leap year =366 days
1 day = 24 hours
1 hour = 60 minutes
1 min = 60 seconds
therefore,
1 year = 365 *24 hours= 8760 hours
For Non leap year:
1 year = 365 days
