# How many minutes are in a day? Know Some Mind-Blowing Facts about Time and its Calculation

Have you ever wondered how many minutes are in a day? It’s a question that might seem simple. However, the answer to this can be actually quite mind-boggling. Most of you would probably guess that there are 1,440 minutes (24×60) in a day. However, it is not quite accurate. In fact, the exact number of minutes in a day varies depending on a few factors.

You should note that the exact length of a day varies slightly due to factors such as Earth’s orbit around the sun/ rotation speed, etc. These factors result in a deviation of 4 minutes. In this post, we are going to discuss the complete details related to the number of minutes in a day.

## Understand the term “Minute”

The word “minute” comes from the Latin word “minutus”. The literal meaning of this word is “Small” or “Little”. A minute is a unit of time equal to 60 seconds or 1/60th of an hour. This unit is commonly used to measure short periods of time. For example, we measure a phone call/ time taken to complete a task in minutes.

Generally, there are 60 seconds in a minute. However, due to the addition of leap seconds, a minute can have 61 seconds occasionally. Leap seconds are added to synchronize atomic clocks with the Earth’s rotation. The addition of leap seconds is necessary because the Earth’s rotation is gradually slowing down. Still, the most accepted fact is that 1 minute has 60 seconds.

## Duration in a Day

In simple language, we can say that the duration of a day is the amount of time it takes for Earth to complete one rotation on its axis. This period of time is approximately 24 hours. However, it can vary slightly due to a number of factors. These factors include Earth’s rotation rate/ length of the solar day.

Nonetheless, for practical purposes, a day is generally considered to be 24 hours long. The duration of a day is an important concept in a variety of fields including astronomy, physics/ timekeeping, etc.

## Calculation ofHow many minutes are in a day?

The exact number of minutes in a day is 1,440. This number is derived by multiplying the number of hours in a day i.e. 24 by the number of minutes in an hour i.e. 60. So, 24 x 60 = 1440 minutes in a day.

This number can be further broken down into smaller time duration. For example, there are 60 seconds in a minute. So, there are 86,400 seconds (1440 x 60) in a day.

Furthermore, we can take a look at the number of minutes in a week. We know that there are 7 days in a week. So, there are 7 x 1440 = 10,080 minutes in a week. This calculation can be used to help plan out schedules for the week. Additionally, it will ensure that all tasks and activities are properly accounted for.

In the above calculations, we are not considering the fact that the exact time of the earth’s rotation on its axis is approximately 23 hours, 56 minutes, and 4 seconds. This difference is so small that we don’t usually notice it.
