How Many Seconds in a Day?

To calculate how many seconds are in a day, you first need to know how many hours and minutes are in a day. There are 24 hours in one day, therefor there are 1440 minutes in a day. (24x60) Now if we multiply 1440 minutes by 60 (seconds per minute), we have 86,400 seconds in one day.
