Understanding Preposition of Time
Preposition
Posted by
Prepositions of time are essential in English for expressing when something happens. The most common ones—“at,” “on,” and “in”—each have specific rules. “At” is used for precise times and specific moments, “on” is for specific days and dates, and “in” is for longer periods like months, years, and centuries.
Understanding how to use these correctly will improve both your spoken and written English. In this guide, we’ll explore their differences with clear examples to help you master prepositions of time.
