If it's 7:30pm, which of these phrases is correct, Good night or Good evening?

Depends on context. "Good night" is generally reserved as a replacement for "goodbye". "Good evening" is a form of "hello".

    "Good evening" has historically been a way of saying goodbye as well, but in modern usage both "good evening" and "good day" used as a goodbye is almost always a form of dismissal rather than a mere parting (particularly when accompanied by a formal form of address, e.g., "good evening to you, sir!").

    Wonder if the meaning is different based on dialect. I've never heard Good Evening used as a way to say goodbye. In my experience, Good Morning is a hello, Good Afternoon is a hello, Good Evening is a hello, Good Day is a goodbye and Good Night is a goodbye. Good Day I've heard more often in the dismissal tone though, unless "Have a" comes before it. Feb 18, 2011 at 5:02

    I agree. In my personal dialect I use all of them for hello and goodbye, I could even envisage using any of them as a dismissal :D Feb 18, 2011 at 10:52
  • So if you meet a person at 11 or 12 in the night, are you still expected to greet the person with "good evening"? Somehow saying "good night" to greet them seems incorrect.

  • Yes, I would still use "good evening" at 11 or 12 at night. Once you cross into 12am and later though, good morning becomes viable and more likely the closer you get to 12pm. If I'm at the end of my day, 1am = good evening. If I just woke up, 1am = good morning. That's the context I would associate with which to use. Mar 29, 2017 at 18:14

"Good evening" is something that can be used from roughly 5 PM on. "Good night" can also be said from 5 PM on, but usually means one of two things:

  1. "goodbye (for the rest of the day, because we are leaving work, the bar, etc.)"

  2. "I'm going to bed now and/or "you're going to bed now" (said to family members, people I am chatting with online or on the phone, when one or both of us is going to bed)"

It basically never means "hello (late evening)" that equivalent phrases can have in other languages.


My answer from a similar, before someone pointed to this as a related question, to which this is even more suited:

"Good night" as a greeting was once commonly found in Ireland, but almost exclusive to there. In James Joyce's "The Dead", for example, it is used both as greeting:

—O, Mr Conroy, said Lily to Gabriel when she opened the door for him, Miss Kate and Miss Julia thought you were never coming. Good night, Mrs Conroy.

And as a farewell:

—Well, good night, Aunt Kate, and thanks for the pleasant evening.

I suspect, but do not know for sure, that this was a retention of something that was more widespread, but died out elsewhere sooner than in Ireland.

In any case, it has mostly died out here too. It may be heard from an older generation, and perhaps lingers in some regions, but my generation (mid 30s) wouldn't use it either in the region I grew up, nor where I now live.

"Good evening" would be the more normal night-time greeting.

The only logical explanation I can think of for our no longer using "good night" in this way, is that it is so often said to someone about to retire to bed, that it was hence used more often as a farewell and then came to have only this meaning. The other forms, after all, would be more often used as a greeting than a farewell, though historically that was not the case.


So far as I know, there is no generally accepted definition of the exact times that evening starts and ends.

As others have said, good night is most often used when parting. If you said this at 7:30 people might respond "goodbye" and turn away.

As you enter the home of a friend, you might say good night to someone leaving and good evening to your host (assuming it isn't the sort of occasion where "wassup hussler" and "yo bitch" are appropriate).

  • I shall henceforth replace goodbye with one of the aforementioned phrases. "Yo bitch" will be used in place of goodnight and "wassup hussler" will be used as a replacement for good afternoon.

Good evening can be used to say hello or goodbye depending on the context. Good evening can be used to say hello once it gets dark outside and the time varies depending on the season. Good evening can be used to say goodbye usually just after it turns dark outside. Good night is usually used to say goodbye later on at night when people separate for the rest of the evening/night.


As per my knowledge and experience: good morning; good afternoon; good evening; hello etc. to say or greet the person for the first time on that day.

Even if you are meeting a person at 10 p.m. at night, the first time of the day, you can still greet him/her with "Good morning". This means it's a positive, well wishing statement, that's all. As somebody has pointed out already, when two people part company for the rest of the day, then "Good night" is the correct one. (Any comment, please correct me if I am wrong.)

Similarly, dinner is not only for night food, it's just a meal, you can say it in the morning, afternoon or night. But, in this case, it's clear in the morning we say breakfast; afternoon-lunch, and dinner means night :)

  • (Not my downvote, although I agree with it) Perhaps greeting someone at 10 o'clock at night with "good morning" is acceptable in your dialect, but in BrEng and AmEng you would get some odd stares, and be perhaps corrected: "You mean, "good night"?"

  • Ah, the dreaded As-per Syndrome strikes again. Please note that beginning sentences with As per looks like a super-stuffy affectation, really pretentious as all get out. Its As in completely superfluous. It would just be Per my experience but even that is painfully stuff. Just say In my experience. And using knowledge there with As per makes no sense at all.
