**How Many Seconds in a Day**: Do you want to know how many seconds are in a day before organizing your day and getting things done on time? It is 86,400 seconds. About the Earth’s rotation, 24 hours seems like a long time. That’s right.

If you are looking for how many seconds in a day, the earth rotates on its axis in just 24 hours. What exactly does that mean? It takes 23 hours, 56 minutes, and 4 seconds for the Earth to complete a rotation. The length of a day or year depends on whether you are traveling along the Earth or stationary on the Earth’s surface.

## How Many Seconds in 24 Hours

Our earth has a speed of 107,000 miles per hour. This movement causes time zones and makes the time differs depending on where you are on the planet.

Time seems to fly almost unnoticed, yet we know its passage is measured in seconds and minutes. We hope you understand how many seconds are in a day.

## How Many Seconds in a Day

A day is twenty-four hours long, and each hour has sixty minutes. One minute is 1/60th of an hour, and one second is 1/60th of one minute. There are 365 days in one year and 86,400 seconds in a day. This makes the total number of seconds in a year equal to 31,536,000.

A day is 86,400 seconds. This may seem like an astronomical number – after all, there are 24 hours in a single day – but it’s tiny compared to the number of particles in the known universe: 10 followed by 22 zeros!

If you watch 24 hours straight and count, you’ve watched just over 142 minutes of video. That is about 15 short films or 3 1/2 feature films. One glance at the clock shows that a day is 24 hours long. In a day, every hour has sixty minutes, and every minute has 60 seconds, so 24 hours per hour x 60 mins x 60 secs per minute = 86,400 seconds in a day. So now we have how many days are in a year and how many seconds are in a day (86,400).

## How Many Seconds in 24 Hours

With some simple formula, it is possible to calculate precisely how many seconds there are in a year. Earth rotates once every day. If we divide those rotations by the number of seconds in a rotation (86,400), we get the approximate number of seconds per year:

- 31556925 seconds or about 31 million, 569 thousand, and 25 seconds.
- To determine how many days are there in a year, divide that number by the number of seconds in a day (86,400).
- Approx 365 days and 6 hours per year.

Not counting the leap years, there are about 86,400 seconds in one day. However, when you count the leap years, there are 86,400 + 1 = 4 x 86,400 = 3596000.

There are 24 hours a day. In other words, if you multiply one by 24, you get 24 because the hour hand on your watch passes through 12 positions 24 times.
