# How many seconds in a day.

It’s good to clarify first that when we refer to a day we could mean one of these two types of a day. A civil day which has 24 hours,

Or

Civil day is also known as conventional day. We are going to calculate for both types of a day.

A solar day is a full Earth’s rotation around it’s axis and it takes 23 hours 56 minutes and 4.1 seconds. Now when you compute the total number of seconds in a solar day you get 86164.1 seconds.

Done like this,

23 hrs = 82,800 seconds. 59 minutes has 3360. So, 82800 seconds add the 3540 seconds and 4.1 seconds totals 86164.1 seconds per solar day.

To compute the number of seconds there is in a civil which is also called the conventional day we do this;

The conventional day has 24 hours.

The day has 24 hours and each hour has 60 minutes. One minute equals 60 seconds. Now to get the number of seconds in a day you multiply hours by minutes by seconds.

24 hours multiplied by 60 minutes multiplied by 60 seconds.

The equation should look something like this 24x60x60.

The answer should come to eighty-six thousand, four hundred seconds per day. 86400 per civil day. You can multiply that by 365 to get seconds per year.
