How many seconds in a day and its correct calculations

On some known questioning platforms. There was a question stating “How many seconds in a day?”. Since this question has now become a very interesting topic nowadays. This is because most users get confused about doing so many calculations that are at their fingertips.

Some confusions regarding how many seconds in a day

Hence, the question of “How many seconds in a day” is very difficult to solve only with brain skills. However, some mathematicians who are used to calculating values in their brains can easily solve this question. On a well-known website, a mathematician was asked the question “How many seconds in a day”. He straight away answers that a day has 86,400 seconds in a day. This was amazing because there are around 4 to 5 long multiplications which the mathematician needs to do too at their fingertips.

Mathematician Proven Wrong

This Mathematician was then proven wrong by repliers in the comment section of that website. That mathematician had made an illogical mistake in his calculation. His reply to the question “How many seconds in a day” goes as 80*60*24=86,400. This calculation is half correct but half wrong as well. He had multiplied sixty and twenty-four correctly.

However, the figure of 80 had been used. It should instead be sixty. This is because there are 60 seconds in a minute not 80 seconds in a minute. Hence his answer to the question “How many seconds in a day” was wrong. The final answer should have been 115,200 instead of 86,400. Still, some users were reminding this mathematician by commenting repeatedly so the mathematician recognized his mistake.

Correct Calculation

There are different solutions to the question on every website. On another website, they had a separate article on “How many seconds in a day”. Their calculation goes as follows. They first define the info given that a day has twenty-four hours in it. Then an hour has sixty minutes in it. Lastly, they state that one minute has around sixty seconds in it. Hence, they continue by multiplying twenty-four with a square of sixty. The square of sixty is mainly used because the specific value is easier to remember. Finally, they answered that there are around 86,400 seconds daily. This is the correct answer to the question “How many seconds in a day”.

Scientific Explanation

An anonymous user even gave a scientific explanation of the question “How many seconds in a day”. They started by stating that in a day there are approximately 86,400 seconds. However, the earth’s full rotations take a little over 24 hours. They stated that the earth takes exactly 23 hours, 56 minutes, and 4 seconds for a full rotation.

Hence, this produced a twist in the question of “How many seconds in a day”. They further stated that the figure of 23 hours, 56 minutes, and 4 seconds is an astronomy figure which is not used on the earth itself. This is because this specific time is measured while being in space. There is also a time difference which covers up the remaining 3 minutes and 56 seconds. Hence, there are only 24 hours in a day.


The final answer to the question “How many seconds in a day” is 86,400 seconds. This is the final answer confirmed by physicists, astronomers, mathematicians, and even known professors around the globe.
