Time help . . when night starts and ends. .?

Question

When is it a new day and when is it night?

ok i was thinking. .

midnight starts at 12 00

so if "mid" night started at 12 00

would night begin at 6 00 PM and end at 5 59 AM?

and would day begin at 6 AM and end at 5 59 PM?

and since 12 01 is technically a new day would the day start off as night?

me and my friend were arguing whether this is true or not. .

ok these answers are great but its not helping me so im gonna add this detail . .

if the sun does come up at 6 AM and sets at 6 PM

would night begin at 6 00 PM and end at 5 59 AM?

and would day begin at 6 AM and end at 5 59 PM?

and lets say

theoretically speaking lets say midnight is when its the "Middle of the night"
and Noon is "the middle of the day"
since there is 24 hours in a day
would 6:01 PM be the beginning of night time and 5:59 the end of nighttime
and 6:00 AM the beginning of day and 6:00 PM the end of day. .

and since we consider 12:01 a new day. theoretically would the day of the week start off in night then daylight then night again?

just something to ponder about. .

Answer 2

When night and day start is a convention that is different in different cultures. In modern times we say that the start of a new day is 12:00 AM, or the middle of the night. However, in other cultures, the next day is believed to start at the beginning of night (sundown). This is the reason we celebrate so many "eve" holidays (Christmas eve, Halloween or All-Hallow's Eve); in ancient times, that was the start of the holiday. The problem with starting a day in the evening or morning, is that those times vary throughout the year.

Answer 3

Simply put - Given sunrise and sunset vary every day so these times change. Time is the measurement that separates one event from the next. So in some cultures, a day is from sunrise to sunrise. As already mentioned some cultures start their days at sundown the previous day. Sine world time follows a 24 hour clock, ie 0100, 0200, 1400 etc, a day starts at 12 midnite. At midnite we celebrate New Years so it is given the "day starts at midnite or 12 am./ In military logs, this is reflected as 0000 hrs not 2400. In actuality, the logs go from 0001 to 2359 hours.
Sunrise starts the new day daylight, sunset ends the day and Twi light or evening begins. Night is when you see no evidence of sunlight in the west. Time therefore is relevant to how you wish to measure it.

Answer 4

I can see your problem. You face two complications:

First - it's a linguistic problem. A "day" has two meanings. a) a 24hr period from midnight to midnight (as in "seven days a week") b) the hours of daylight (as in "day and night")

Second - it's a problem of numbers. In the USA you are still stuck to a.m. and p.m. - this does not help you. It is much easier to work in the international notation where the day (as 24hr period) starts at 00:00:00.0 and ends at 23:59:59.9

Answer 5

I think the day/night division is not based on time but is based on the Sun rising and setting. So your answer depends on where you are on Earth latitudinally and longitudinally and what season it is. Day does not end and night does not start at the same time everyday, nor does it start at the same time for two different cities in the same time zone but different latitudes and longitudes!!! If you are at the North Pole and it is summer, night never starts! The day lasts for 3 months, i.e., 3 months of straight sunlight!

Answer 6

It depends on your definitions....

Technically for basically any two seperate points you pick on the face of the earth the sun will "rise" at a different time.

The sun is either present in the sky or it is not... the clock hours were invented by man.

Answer 7

those numbers are for simplicity. it depends on the position of the earth etc. Night is when the sun is no longer visible. Where i live (brisbane australia) thats about 1715 at the moment as its the middle of winter.

The numbers you talk about are simply there for scheduling. we define "night" its not actually a thing.

Answer 8

12:00am midnight = new day
12:00pm day time = night
