beginning of a new day that is why it is called 12:00am
It's technically called "Limbo" for that split second it is at midnight. At noon, the split second is called "Purgatory."
I honestly think the start of a new day but it depends on who were talking about-Lol
I guess it is said midNIGHT because there is no day light. But since it is also said to be A.M. THEN,
Why don't we just call it MIDNIGHTMORNING! HEE HEE HEE
Well, technically, the new day started 3 minutes and 56 seconds prior to midnight if we are looking at the sidereal day.
The start of a new day...
