The civil hour is 86400s. It takes 24 h x 60 min. X sixty s. This is the average solar day, slightly shorter (milliseconds). The International Earth Rotation Service or the Time Lords (the Time Lords) creates an 86401 day by declaring a leap second on June 30 and Dec 31 when the decimal dust reaches a full sec.

There is also a sidereal hour, measured by rotation relative to fixed stars rather than the sun. It takes just a few more minutes (almost 4) less. Astronomers only care about this.

Calculate seconds per day.

One day is 86400 seconds.

Calculation of Seconds in a Day
1 day = 24 hrs

1 hour = 60 Minutes
1 minute = 60 Seconds


1 day

= 24 hours/day, 60 minutes/hour, 60 seconds/minute

= 86400 seconds/day.

One minute has 60 seconds. One hour has sixty minutes; one day has twenty-four hours. 60 seconds divided by 60 minutes and 24 hours gives you 86.400 seconds.

One calendar year can have 365 days.
Thus, 31563,000 seconds can be calculated by multiplying 365 by 86,400.

Number of seconds per day
Everybody knows that a day has twenty hours, representing the time it takes for the earth’s axis to rotate. This revolving movement is related to the sun and gives rise to SI, the unit used in the metric.

How many seconds is one day?

Let’s take a step by step look at the calculation of seconds in a single day.

Per Minute

Time, and especially seconds, can be calculated back to Babylonian time. Scientists say that 60 seconds equals one minute. Surprisingly though, this unit does not exist.

However, if we look at history in isolation, we can see sixty minutes per hour. And to better understand the time it takes for a day to pass, let’s do some math.

Here’s a simple calculation to help you get started:

One minute = 60 seconds

One hour = 60 seconds

60 x60 = 3600 second

Each day has 24 hours. If we measure the number of seconds in an hour, we get a total of 3600. Therefore, to calculate the total time of all 24 hours of a 24-hour day, we need to multiply 3600 with 24.
