Why does a new day start at 12 instead of 1?

The reason a new day starts at 12:00 goes back to ancient Egypt when the day was measured using sundials. Since the highest point of the day was noon, the opposite has to be midnight that was when the 12 started over again, so that’s why the day starts at midnight.

Does a new day start at 12 am or 1 am?

The new day begins at the beginning of 12:00:00 AM, not the end of 12:00:00 AM. Because most clocks will pause for one second (all clocks pause for a time, depending on how accurate it is will determine for how long) before changing to the next second. Time itself does not pause.

Does a new day start at 0000 or 0001?

The question sometimes arises whether midnight is written as 2400 or 0000. Military and emergency services personnel refer to midnight both ways. However, digital watches and clocks that display time in a 24-hour format and computer equipment treat midnight as the start of a new day and express it as 0000.

Why does the clock stop at 12?

The original 12 hour system used by the Egyptians and Greeks was twelve hours of night and twelve hours of day with the hour length actually changing with the seasons. The twelve number actually comes from Egyptian style finger counting where you count each of three knuckles on four fingers (4*3=12).

Is 0000 the start of a new day?

Another option would be to use 24-hour clock, using the designation of 0000 to refer to midnight at the beginning of a given day (or date) and 2400 to designate the end of a given day (or date).

Where is the first place a new day starts?
