The Preposition “At”
The preposition “at” is commonly used to indicate a specific point in time. It helps to pinpoint an exact moment, making it clear when an event occurs. Here are some of the most common uses of “at”:

2. Mealtimes: “At” is also used to refer to meal times. For instance:
– We often have dinner at 7 PM.

The Preposition “On”
The preposition “on” is used when we want to refer to specific days or dates. It helps to situate an event in a more defined timeframe than “at.” Here are the common usages of “on”:

The Preposition “In”
The preposition “in” is used for longer periods of time, such as months, years, centuries, and longer periods. It provides a broader context for when an event occurs. Here are the main uses of “in”:
