Prepositions are an essential part of the English language, helping to clarify relationships between different elements in a sentence. Among the various types of prepositions, those that denote time are particularly crucial for effective communication. Understanding and correctly using prepositions of time can significantly enhance your fluency and accuracy in English. In this article, we will delve into the most common prepositions of time, providing detailed explanations and examples to help you master their use.
Common Prepositions of Time
At, On, and In
Among the prepositions of time, at, on, and in are perhaps the most frequently used. Each of these prepositions serves a distinct purpose and is used in different contexts.
At is used to denote specific points in time. For example:
– “The meeting starts at 3 PM.”
– “I usually go to bed at midnight.”
On is used for days and dates. For example:
– “We have a test on Monday.”
– “Her birthday is on July 21st.”
In is used for longer periods of time such as months, years, centuries, and long periods. For example:
– “I was born in September.”
– “The company was founded in 1990.”
– “Many historical events happened in the 20th century.”
By and Until
By and until are often used to talk about deadlines and the duration of time.
By indicates a time before or at a certain point. It is often used to set deadlines. For example:
– “Please submit the report by Friday.”
– “The project should be completed by the end of the month.”
Until (or till) indicates the duration up to a certain point in time. For example:
– “You can stay until the movie ends.”
– “I will be here until 5 PM.”
During, For, and Since
These prepositions are used to specify periods or durations of time.
During is used to specify a period of time in which an event occurs. For example:
– “I read a lot during my vacation.”
– “There was a lot of noise during the concert.”
For is used to indicate the duration of an action or event. For example:
– “I have lived here for five years.”
– “She studied for three hours.”

– “He has been waiting since noon.”
From…to, From…until, and From…till
These expressions are used to denote the beginning and end of a period.
From…to is used to indicate the start and end points of a period. For example:
– “The museum is open from 9 AM to 5 PM.”
– “I will be on vacation from Monday to Friday.”
From…until and from…till are similar to from…to but are often used in more informal contexts. For example:
– “She worked from morning until night.”
– “The event lasted from 6 PM till 10 PM.”

By the Time
By the time is used to indicate that one event will be completed before another event happens. For example:
