Why does the new day begin at 12 o’clock at night?

Time is a big topic, it has a lot of importance in science.

Our days depend on the needles of the clocks, that is, what time has come, what time to do, etc.

But the question is, why does the new day start at 12 o’clock in the night (according to the Gregorian or Julian calendar)?

The answer is not simple, but quite confusing, but it is clear that it happened by the grace of ancient Rome.

To explain this, you first have to understand AM and PM.

AM is an abbreviation for the Latin phrase ante meridiem which means before noon or b4 noon.

As far as PM is concerned, it is an abbreviation for the Latin phrase post meridiem which means after noon or after noon.

In ancient Egypt, the day was divided into 24 parts or hours and the sun’s position in the sky was taken into account to determine the time.

This system is now called sundial, and since the sundial system could not work at night, it was necessary to determine noon and midnight, for which terms like AMPM were used (at that time, however, it was called something else).

Sundial was invented zero or 0 to 1,000 years ago, so the number 12 was used for the middle part of the day.

In ancient Rome, the SYSTEM of AM and PM was adopted and according to it, two groups of 12 hours each were formed, i.e. 12 hours of day and 12 hours of night.

In 159 BC, a water clock arrived in Rome, which could tell about 12 hours of the night.

Because of this, the Romans started a new day from midnight for business and social engagements, because there were no engagements at that time of the night.

The Romans believed that changing the date in the afternoon would be very confusing, such as eating lunch on Tuesday and returning to work on Wednesday, which could cause various problems.

In this way, gradually it became a tradition and still there is no change in it.
