say goodbey

As is the case with good night, confusion arises when evening begins. Depending on which part of the world you're living, evening can start as early as three (3pm). However it is accepted in astronomical terms that evening starts before sunset and ends at night. This translates to either 5pm or 6pm when evening starts. Thus, when you wish someone to have a good evening it implies it is not yet night - the start of the hour which the majority of people sleep. The same case applies with morning. Does it begin at three (3am) or five (5am)?We can't specify the time but we can tell from observation when the sun sets and rises to determine the morning, evening and night. see more at <a href="https://www.goodmorningsimages.com/2020/03/have-a-good-night-quotes-with-gif.html">How to say have a good night?</a>

Sorry - I think that all the previous answers missed one point. 'Have a good night' can be very different to 'good night'. 'Good night' you say at the end of the night. 'Have a good night' is something you can say to someone BEFORE the night/evening. It would be typical to say it to someone who is going out, and you know that they are going out, or have talked about it. So - you could say it to someone who is going out to a bar that night, when you see them at lunch time 'Bye - and have a good night'.

If it is in the evening, you can say "have a good night", as a way to end a conversation. It is a friendly way to let someone know you are hoping they have a happy evening. Another time you might use it, is if someone is going to sleep. Say for example, if your sister says she is going to sleep, you can tell her to have a good night. No matter how you use it, it is a friendly gesture and is used mostly when you do not expect to see them for the rest of the evening.

Saying it at night after like finishing a conversation so you say have a good night
