Morning moves into afternoon at noon. However, there are no absolute set times for when afternoon becomes evening (usually sometime between 4pm and 6pm), when evening becomes night (usually between 9pm and 10pm) or when night moves into morning (usually between 4am and 6am).
Although the sources appear to contradict each other, either could be considered correct because it is all down to the viewpoint of the individual.
Having said that, I definitely wouldn’t subscribe to the view that morning starts straight after midnight. There are several more hours of night to go first!)
As a general rule, assuming you aren’t working a night shift or other strange hours:
Say Good morning any time between getting up and noon.
Say good afternoon any time between noon and 5pm
Say good evening any time between 5pm and 9pm as a greeting.
Say good night any time after 5pm and bedtime as a farewell.
Say good night any time after 9pm and going to bed.
I think I’ve heard wordings along these lines: At 1:00 in the morning.
When I first encountered it, I was dumbfounded, because at 1:00 am it’s still night in my book.
Iam traveling to Monrovia on an ugent trip starting from Sept 18,October 6,2010 to settle some Financial obligation with the Ministry of Health and Social Welfare .During this period ,all financia issued requiring my attention should be directed to the Hospital Administrator,Mr Lousina F.Farwenel.
I see “morning” as having two distinct meanings. One is the time between midnight and noon, and the other is all daylight before noon.
A fire that takes place at 3 a.m. may be said to take place in the middle of the night. It could just as soon be said to be an early-morning fire. I wouldn’t argue with either.
As for evening and night, my view of the distinction shifts with the seasons. I would definitely consider 7 p.m. nighttime in the winter. I might even say 6. Where I live, it gets dark at 5 for much of winter. In the summer, however, I would find that absurd. I would say night begins at 9 in the summer.
