## How to calculate the number of seconds in a day?

The formula to calculate the number of seconds in a day is = hours per day x seconds in a minute x minutes in an hour. These time units are known as:

- 1 day = 24 hours
- 1 hour = 60 minutes and
- 1 minute = 60 seconds.

**The number of seconds in a day = 24 hours in a day x 60 minutes x 60 seconds = 86,400 seconds.**

### How many seconds in a hour?

There are 3600 seconds in an hour. The formula to calculate the seconds in an hour is number of minutes in a hour x number of seconds in a minute = 60 x 60 = 3,600 seconds.

### How many seconds in a week?

To calculate the number of seconds in a week, use this formula:

7 (days in a week) x 24 (hours in a day) x 60 (minutes in an hour) x 60 (seconds in a minute) = 604,800 seconds in a week.

### How many seconds in a month?

To calculate the number of seconds in a month, use this formula:

30 (days in a week) x 24 (hours in a day) x 60 (minutes in an hour) x 60 (seconds in a minute) = 2,592,000 seconds in a 30 day month.

For this calculation we considered a 30 day month. Let's see the other options:

31 days month = 2,678,400 seconds

29 days month = 2,505,600 seconds

28 days month = 2,419,200 seconds

### How many seconds in a year?

To calculate the number of seconds in a year, use this formula:

365 (days in a common year) x 24 (hours in a day) x 60 (minutes in an hour) x 60 (seconds in a minute) = 31,536,000 seconds in a common year.

Note, leap years have 366 days, and in seconds this means 31,622,400 seconds in leap year.
