MIDNIGHT

Midnight is the transition time from one day to the next – the moment when the date changes, on the local official clock time for any particular jurisdiction. By clock time, midnight is the opposite of noon, differing from it by 12 hours.

Solar midnight, or dark night,[not verified in body] is the time opposite to solar noon when the Sun is closest to the nadir, and the night is equidistant from dusk and dawn. Due to the advent of time zones, which regularize time across a range of meridians, and daylight saving time, solar midnight rarely coincides with 12 midnight on the clock. Solar midnight depends on longitude and time of the year rather than on time zone. In ancient Roman timekeeping, midnight was halfway between sunset and sunrise (i.e., solar midnight), varying according to the seasons.

When someone refers to "midnight tonight" or "midnight last night" the reference of time is obvious. However, if a date/time is referred to as "at midnight on Friday, October 20th" the intention could be either midnight the beginning of the day or midnight at the end of the day.
MIDNIGHT is 12pm. One must recognise the difference between points in time and periods of time. Midnight is the zero point in time when we start to build up 24 one-hour periods of time to make up a new day. So midnight is the point 0am. After a period of one hour we reach the point in time called 1am, and after 12 periods of one hour we reach the point called noon. At noon the 13th one-hour period starts, ending at point 1pm. This process continues up to the point 11pm when the 24th period of one hour starts. This period ends in the middle of the night, 12 hours after noon at the point midnight or 12pm.
The 12-hour system divides the 24 hours of a day into two periods lasting 12 hours each. The first 12-hour period is designated as am. It runs from midnight to noon. The second period, marked pm, covers the 12 hours from noon to midnight.

The abbreviations am and pm derive from Latin:

AM = Ante meridiem: Before noon
PM = Post meridiem: After noon

Using numbers from 1 to 12, followed by am or pm, the 12-hour clock system identifies all 24 hours of the day. For example, 5 am is early in the morning, and 5 pm is late in the afternoon; 1 am is one hour after midnight, while 11 pm is one hour before midnight.
Les Lavandières, or the Midnight Washerwomen, are three old laundresses in Celtic mythology. Names in various Celtic languages include the kannerezed noz in Brittany and the Bean nighe in Scottish. They can also be found in the Celtic folklore of Iberia as Las Lavanderas in Cantabria, As lavandeiras in Galicia or Les Llavanderes in Asturias. The three old women go to the water's edge at midnight to wash shrouds for those about to die, according to the myth and folklore of Brittany; or to wash the bloodstained clothing of those who are about to die, according to Celtic mythology. The Midnight Washerwomen may be related to the old Celtic tradition of the triple goddess of death and slaughter.
