Do you need a comma after year when it is in prepositional phrase of less than five words?

You don't need a comma after the year when it's part of a prepositional phrase of less than five words.

Here's why:

* Prepositional phrases are groups of words that start with a preposition (like "in," "on," "at," "during," "before," etc.) and end with a noun or pronoun.

* Short prepositional phrases (usually less than five words) are generally considered to be part of the main clause and don't require a comma.

Examples:

* Correct: The meeting will be held in 2024.

* Correct: We arrived at 10:00 AM.

* Correct: The package arrived on Friday.

However, if the prepositional phrase is longer or complex, you may need a comma.

Example:

* Correct: The meeting, held in 2024 at the Grand Hotel, was a success.
