Unit 6.2

Prepositions of Time


Prepositions are small words that connect elements in a sentence. They are essential because they provide additional details about the sentence.

We use prepositions of time to locate an event in a time frame {see Common Prepositions, A1 level}.


Prepositions of time don’t stand alone but act with other elements of the sentence to create what we can call prepositional phrases: at, on, in and by.



  • Everyday at 7.00 clock I can see the stars.
  • He is going to the forest at Easter.
  • At weekends we take the dogs for a walk.


  • On Sundays, I usually relax with my friends by going to the coast.
  • She was born on the 1st of September in 1997.
  • The island sank on Sunday morning.


  • I always travel to famous forests in Finland in November.
  • In autumn it always rains.
  • In the evening the horses started to run.


  • Please, send me those tickets by Monday.
  • She has to finish her world map by next week.
  • Is Maria still in the garden? Yes, she will be back by evening.


We use prepositions of time to locate an event in a specific moment or period.


  • Exact times (the momentsunrisenoonnightmidnighthours);
  • Special holiday periods (Christmas*, Easter…);
  • Weekend*.


  • Days of the week (MondaySaturdayWednesday…);
  • Dates;
  • Specific part of the day (on Sunday morning).


  • Months, years, centuries;
  • Seasons;
  • The morning, the afternoon, the evening.


  • Time-limited actions;
  • Projects with deadline;
  • Time of someone’s return.

*In American English you can find on instead of at.


Prepositions of time are used to locate the event in a time context.

The main prepositions of time are: at, on, in and by.

For example:
— “I will go to my grandparents’ house at Christmas.” = We use at to talk about special holiday periods.
— “I will go to my grandparents’ house on25th of December.” = We use on to talk about dates.
— “I will go to my grandparents’ house in December.” = We use in to talk about months.
— “I will return from my grandparents’ house by December.” = We use by to talk about the time of someone’s return.

NOTE: In American English you can find Christmas and weekend with on instead of at.
