A preposition is a function word that is placed before a noun or anything equivalent to a noun. Prepositions are used to create a connection between the noun and the other words of the sentence.
Example: My cousin will come on Monday.
In the above example, “On” is the preposition. The preposition is used to create a link between the noun “Monday” and the rest of the words. As “Monday” refers to a specific time, we call it a preposition of time.
“At,” “On,” and “In” are the three most common prepositions of time that we use before any noun in a sentence to create a time connection between the object (noun) and the rest of the other words in the sentence. A preposition of time helps us understand any specific year (In 2001), month (In July), date (On 26th June), day (On Sunday), time (6 o’clock), etc.

Though prepositions are one of the significant parts of speech that we use in most sentences, I find many of my students make mistakes in using prepositions. I have already mentioned the primary uses of prepositions of time in the above table.
However, there are some other uses too. In this post, I will share some essential rules and relevant examples for each rule that will surely help you learn prepositions of time: At, On, and In.
