what is difference between by and until
Thank you
'by' is used when not later than the time mentioned; beforeOriginally Posted by Hank
e.g. Can you finish the work by six o'clock?
'until/till' is used when up to the point in time or the event mentioned.
e.g. Let's wait until someone answers. :wink:
by + a time means "not later than"Originally Posted by henry
e. g. You must be home by midnight.
You cannot use until with this meaning.
Call me by 3 o'clock. NOT Call me until/till 3 o'clock.
Something continues until a time in the future.
e. g. I will stay up until you get home.
Something happens by a time in the future.
e. g. I will have gone to bed by the time you get home.
