When learning English, one of the fundamental aspects to master is the use of prepositions. Prepositions are words that show the relationship between a noun or pronoun and other elements in a sentence. Among the various types of prepositions, prepositions of time are particularly important as they help us indicate when something happens. This article will delve into the nuances of prepositions of time, exploring their correct usage through explanations and examples.
Basic Prepositions of Time
Prepositions of time include words like at, on, and in. Each of these prepositions has specific rules and contexts in which it is used.
At
The preposition at is used to specify a particular point in time. It is often used with precise times on the clock and specific points in the day. Here are a few examples:
– We will meet at 3 PM.
– The party starts at noon.
– I usually go to bed at midnight.
– The store opens at 9 o’clock.
At is also used in common phrases like at the weekend, at night, and at Christmas:
– I have plans at the weekend.
– They prefer to work at night.
– We exchange gifts at Christmas.
On
The preposition on is used to refer to specific days and dates. Here are some examples:
– Her birthday is on Monday.
– We have a meeting on the 15th of August.
– The concert is on New Year’s Eve.
– I will see you on Friday.
On is also used for specific days combined with part of the day:
– She works on Monday mornings.
– They visited us on Sunday afternoon.
In
The preposition in is used for longer periods of time such as months, years, centuries, and long periods. Examples include:
– He was born in July.
– They got married in 1999.

– We will travel in the summer.
In is also used for parts of the day:
– She likes to jog in the morning.
– We will have a meeting in the afternoon.
– They go out for dinner in the evening.
Other Prepositions of Time
Apart from at, on, and in, there are several other prepositions that indicate time. These prepositions include before, after, during, until, by, and for.
Before
The preposition before is used to indicate a point in time that precedes another event:
– We arrived before the show started.
– She always has coffee before work.
– Finish your homework before dinner.
After
The preposition after indicates a point in time that follows another event:
– We will go out after the meeting.
– She felt better after taking the medicine.
– Let’s have dessert after dinner.
During
The preposition during is used to specify a period of time in which an event happens:
– He fell asleep during the movie.
– The store is open during the holidays.
– They met during the conference.
Until
The preposition until (or till) indicates a point in time up to which something continues:
– We waited until the last minute.
– She will be in the office until 5 PM.
– The store is open until midnight.
By
The preposition by is used to indicate a deadline, meaning that something should happen before a certain time or not later than a specific time:
– Submit your report by Friday.
– The project must be completed by the end of the month.
– He promised to be back by 10 PM.
For
The preposition for is used to indicate the duration of time an action continues:

– They have been friends for ten years.
Common Mistakes with Prepositions of Time
When learning prepositions of time, it’s easy to make mistakes. Some of the most common errors include confusing at, on, and in, as well as misusing other prepositions. Here are some tips to avoid these mistakes:
– Remember that at is used for specific times, on for specific days, and in for longer periods.
– Do not use in for specific days or dates. For instance, it’s incorrect to say “in Monday”; the correct preposition is “on Monday.”
– Avoid saying “in night.” The correct phrase is “at night.”
– Do not confuse before and after. “Before” refers to a time preceding an event, while “after” refers to a time following an event.
