Prepositions of time are essential components of English grammar, providing context and specifying when an action or event occurs. They establish a temporal relationship between the noun or pronoun they modify and the verb or other element in the sentence. Common prepositions of time include *at*, *on*, *in*, *for*, *since*, *during*, *until*, *before*, *after*, and *by*. Each preposition carries a distinct meaning and usage, contributing to the overall clarity and accuracy of the sentence.

The prepositions *at*, *on*, and *in* are primarily used to indicate specific points in time. *At* is typically used for precise moments, such as *at 3:00 PM*, *at midnight*, or *at dawn*. *On* is used for days of the week, dates, and specific holidays, such as *on Monday*, *on June 15th*, or *on Christmas Day*. *In* is used for larger time periods, such as months, years, seasons, and decades, for example, *in January*, *in 2023*, *in the summer*, or *in the 1990s*.
