We’ll talk in this course about prepositions of time: At, In and On.
We use at with times: when we talk about a precise time of the day (three O’clock..) or a part of the day (night..). Examples:
– We are leaving at midnight.
– You should get up at 9 O’Clock.
– I will come at the end of this week.
We use in when we talk about long time, or a date (month, year, season..). Examples:
– I was born in 1977.
– I was born in july.
– I was born in summer.
We use on when we talk about a day of the week or a special calendar day. Examples:
– My father’s birthday is on the 20th of june.
– I don’t work on mondays.
