How many seconds on a day?

Answer 1

The length of an Earth's solar day in seconds is: ~86,164.1 seconds*

*The answer is accurate if one solar day is taken to be: 23h 56m 4.1s

23h * 60 = 1,380m > 1,380m * 60 = 82,800s

56m * 60 = 3,360s

4.1s = 4.1s

Therefore: 82,800s + 3,360s + 4.1s = 86,164.1s

Answer 2

There are 86,400 seconds in a day.
