Until is used to talk about how long a situation continues.  If something happens “until” a particular time, then it stops when that time is up.  Americans often pronounce the word as ’til.

  • It snowed from Monday until Wednesday.
  • I’m going to work ’til I’m old.


By is used to say something must happen at or before a specific time.  It often indicates a deadline.

  • My report is due by 5PM.
  • I have to be home by midnight.
