Midnight

Modern Polish, Belarusian, Ukrainian, and Serbian languages preserve this association with their words for "midnight" or "half-night" (północ, поўнач, північ, поноћ) also meaning "north".

Though there is no global unanimity on the issue, most often midnight is considered the start of a new day and is associated with the hour 00:00.

[2] In the United States and Canada, digital clocks and computers commonly display 12 a.m. at midnight.

[3][4] However, the previous 29th edition of the U.S. Government Printing Office Style Manual (2000), in section 12.9, recommended the opposite.

The US National Institute of Standards and Technology (NIST) recommends avoiding confusion altogether by using "11:59 pm" or "12:01 am" and the intended date instead of "midnight" or "12:00 am".
