Prepositions of Time (In, At, On)

Intermediate

After this lesson, you will be able to talk about when things happen or when you do certain things.

Exercise 1

Sentence Practice

I was born in 2000.
Her birthday is in December.

Let’s meet on Friday.
I usually go to the gym on Wednesdays.

I usually wake up at 6 a.m.
We can see the stars at night.

Grammar Focus

In + [period of time]

Use 'in + [period of time]' to refer to an unspecified point in that period of time:

a month: Susan's birthday is in December. [= Her birthday may be December 1st, 3rd, 10th, 25th, 31st, etc.]
a year: She was born in 1969. [= Her birthday may be Jan 25th, February 13th, April 6th, October 21st, etc.]
a season: She was born in the fall.
a part of the day: She was born in the morning.

On + [days/dates]

Unlike 'in', the preposition 'on' refers to specific days:

days of the week: She was born on Saturday.
specific dates: She was born on December 21st.

We put our finger on a specific day of the calendar:

At + [specific times]

Use the preposition 'at' to talk about a specific time.

She was born at 5 o'clock in the morning.
She was born at midnight/noon.
She was born at night.

Note that we say 'in the morning/afternoon/evening' but 'at night'.
