Prepositions of Time

SINCE  + time / point in the past (yesterday, last year)
FOR  + period of time (2 hours/3 days/1 year)
UNTIL up to a point in time
TILL Less formal way of saying until
FROM….TO Use from for the start time and to for the finish time


Since is typically used with perfect tenses.  Use since with the Perfect Tenses to express a point of time in the past up to now.

Example Sentences

  • I’ve known him since I was a child.
  • I’ve had this phone since last year.
  • I haven’t eaten anything since this morning.


When used as preposition of time, for is used with a period of time.  Note that although for is sometimes called a keyword for the Perfect Tenses, it can be used with all the other tenses.

Example Sentences

  • I lived in England for 10 years.
  • I’m only working for 3 hours today.
  • I’m going on holiday for a week next month.


Use until to mean the end time, up to a specific time or a point in time.

Example Sentences

  • I will work until 5p.m. today.
  • I played football until the club closed.
  • I going away on holiday until Thursday. (This means that on Thursday I will be back from my holiday).


Use from to mean the starting time and to for the end or finish time.  Note: To can be a synonym of until and till so it’s perfectly correct to use for with until or till. 

Example Sentences

  • I’m going to be on holiday from 31st August to the 10th of September.
  • The lesson is from 9a.m to 10a.m.
  • The meeting is from 6 o’clock to 8 o’clock
  • I will be at the gym from 11a.m till 12.30p.m.
  • I going to be on holiday from the 1st January till the 8th January.
