In the United States, afternoon is generally the time between noon and 5:00 p.m., and evening is considered anything after 5:00 p.m. There is no set allocation for afternoon and evening, however.

As for when afternoon ends, that would be as soon as evening starts--which isn't QUITE as cut-and-dried as when noon hits and when morning starts and ends (which times aren't up for debate, by definition).
