ADVERBS OF TIME

1. We use adverbials of time to say when something happens. We often use noun groups called time expressions as adverbials of time.

Note that we do not use the prepositions ‘at’, ‘in’, or ‘on’ with time expressions.

One of my children wrote to me today..

So, you're coming back next week?

We often use time expressions with verbs in the present tense to talk about the future.

The plane leaves tomorrow morning.

They're coming next week.

2. We can use prepositional phrases as adverbials of time:

• ‘at’ is used with:
   

  clock times: at eight o'clock, at three fifteen religious festivals: at Christmas, at Easter mealtimes: at breakfast, at lunchtimes specific periods: at night, at the weekend, at weekends, at half-term

  
  
• ‘in’ is used with:
   

  seasons: in autumn, in the spring years and centuries: in 1985, in the year 2000, in the nineteenth century months: in July, in December parts of the day: in the morning, in the evenings

  
  

  Note that we also use ‘in’ to say that something will happen during or after a period of time in the future.

  I think we'll find out in the next few days.

• ‘on’ is used with:
   

  days: on Monday, on Tuesday morning, on Sunday evenings special days: on Christmas Day, on my birthday, on his wedding anniversary dates: on the twentieth of July, on June 21st

  
  

3. We use ‘for’ with verbs in any tense to say how long something continues to happen.

He is in Italy for a month..

I remained silent for a long time.

I will be in London for three months.

WARNING: We do not use ‘during’ to say how long something continues to happen. We cannot say ‘I went there during three weeks’.

4. We use ‘since’ with a verb in the present perfect or past perfect tense to say when something started to happen.

Marilyn has lived in Paris since 1984..

I had eaten nothing since breakfast..

5. We can use many other prepositional phrases as adverbials of time. We use:

• ‘during’ and ‘over’ for a period of time in which something happens

  I saw him twice during the summer holidays.

  Will you stay in Edinburgh over Christmas?

• ‘from...to/till/until’ and ‘between...and’ for the beginning and end of a period of time

  The building is closed from April to May.

  She worked from four o'clock till ten o'clock.

  Can you take the test between now and June?

• ‘by’ when you mean ‘not later than’

  By eleven o'clock, Brody was back in his office.

  Can we get this finished by tomorrow?

• ‘before’ and ‘after’

  I saw him before the match.

  She left the house after ten o'clock.

  ‘Since’, ‘till’, ‘until’, ‘after’, and ‘before’ can also be conjunctions with time clauses.

  I've been wearing glasses since I was three.

  You use the adverb ‘ago’ with the past simple to say how long before the time of speaking something happened. You always put ‘ago’ after the period of time.

  We saw him about a month ago.

  John's wife died five years ago.

  WARNING: We do not use ‘ago’ with the present perfect tense. We cannot say ‘We have gone to Spain two years ago’.
