The Bully Mnemonic reminds us that there are approximately 31556928 seconds in a tropical year:

1TropicalYear31556928sec

1TropicalYear(103300.40)×3055=31556928sec

There are 86400 seconds in a day:

1Day=24hours×60minutes1hour×60seconds1minute=86400seconds

The number of seconds in a 365 day year is:

365Day=365×86400seconds=31536000seconds

The number of seconds in a 366 day year is:

366Day=366×86400seconds=31622400seconds
