Hope this helps! Note: if someone asks you what time it is, and it is x:50 or x:55 (x= any hour), you may answer "ten till" and "five till" and it will be correct. For x:45 you can say "a quarter till" and for x:15 you can say "a quarter past x."
Example:
You: What time is it?
I look at my watch. It's 3:55.
Me: About five till. (About five till four.)
Literally, this means "there are about five minutes until it will be four o'clock."
Me: What time is it?
You look at your phone. It's 2:15.
You: It's a quarter past two.
