What time does nighttime officially begin?

Question

I would like an exact time (example: 7 pm) ect...

Answer 1

What you would like and what you will get are different, unfortunately! The only extent to which "nighttime" has been made "official" is in the soli-lunar calendar, as used today by Jews.. It represents months based on the moon's phases, and each year being a whole number of months. This leads to different lengths of years - some a whole "month" longer than others. Every 19 years is almost (but not QUITE) a whole number of lunar months, so our calendar and the Hebrew calendar are re-aligned after 19 years (called a "Metonic cycle" after the ancient metiorologist, Meton). Our own calendar has different length years -- one extra day nearly every fourth year -- but there is no attempt to align the clock with daylight -- it would be very complex, changing by latitude and at different times through the year. Television listings have decided that "evening" starts at 6:00pm in North America (TV Guide) but at 7:00pm in Britain (Radio Times, TV Times, etc). "Lighting up time" -- the "official" definition of nighttime, one might suppose -- changes by location and date, and are published in tables of "Ephemera" (Ancient Greek for "vanishing things")..

Answer 2

I've always thought it was 6:00pm. a nice mid point

between noon and midnight. -- If you think evening is

synonymous with nighttime, I'd go with 6:00pm.

That's when the evening news begins.



Some cultures consider nighttime to be sundown.

It's too confusing for me. I grew up near Boston where

the consensus seems to agree on 6pm.

Answer 3

According to a free downloadable dictionary called "TheSage", nighttime is the time after sunset and before sunrise while it is dark outside.



Evening, however, begins at 5pm in the USA.

Answer 4

When the sun goes down. I don't think there is an exact time.

Answer 5

I am sorry I can't answer for your country, but in mine, it starts exactly at 7 p.m. (by the way, I am a "browny" mexican)

Answer 6

Real nightlife I would think 10:00pm.
