How many seconds are in a day?

A day has 24 hours, and each hour has 60 minutes. Therefore, a day has a total of 24 x 60 = 1,440 minutes. Since each minute has 60 seconds, you can multiply 1,440 by 60 to get the total number of seconds in a day. This gives you 86,400 seconds in a day. Keep in mind that this is based on the standard 24-hour day and does not account for variations such as leap seconds, which are occasionally added to keep atomic time in sync with the earth’s rotation.
