I know how to tell time, but I just don't understand it when someone says it's "a quarter to 4" or it's "After 6 o' clock," and stuff like that. Does everyone have that kind of problem?? Because I don't remember ever learning how to tell time like that in grammar or elementary school.

Eh, this is just a term of speech to denote different times. For instance, an hour is 60 minutes right? Well, if you broke it into 4 quarters it would be 15 mins each, so when someone says its "Quarter to", that means its 15 minutes away from being that hour. Example: its 4:45p.m. and you ask what time it is, I would answer its, "Quarter to" assuming you knew that it was at least past 4:00p.m., "half after" would be 30 mins after the current hour, so like half after 5 means 5:30. So its basically like applying mathematic terms to short sayings we use in everyday life to denote the time...

But could you give me some web sites on this subject to better help me understand??

These web sites will help you understand telling time better.
