In English, prepositions are essential for expressing time, location, and other relationships. The confusion often arises when we talk about months, such as January, and wonder whether to use at or in.

So, we should always say “in January,” not “at January.”

Common Prepositions Used with Time

Understanding Prepositions in Time Expressions

Prepositions like in, at, and on are frequently used when discussing time. These small words play a crucial role in determining the meaning of a sentence. Here’s a breakdown of how each preposition is commonly used in relation to time:

At: This is used for specific times or moments.
On: This is used for specific days and dates.

For example:

I will visit you in July. (Correct)
The concert is at 7 p.m. tonight. (Correct)
My birthday is on Tuesday. (Correct)

The Correct Usage of “In January”

Definition of “In”

The preposition in is used when referring to months, seasons, years, and other larger time periods. It indicates a general time frame within which an event or action occurs.

For example:

She will visit us in January.
The movie is scheduled to release in January.
In January, we plan to launch the new marketing campaign.

Grammar Rules for Using “In”

There are some simple rules to follow when using in:

Use in with months, such as in January.
Use in for seasons, like in summer.
Use in for years or decades, such as in 2020.

Examples

“He will come in January.”
“The project starts in January.”
“The weather is cold in January.”

Common Mistakes to Avoid

Why “At January” Is Incorrect

Many learners mistakenly say “at January,” but this is grammatically incorrect. This happens because at is used for specific points in time, such as exact hours or specific moments, not for general months.

Explanation of Incorrect Usage

Using at before months, like at January, doesn’t align with standard English grammar rules. The correct preposition for months, such as January, is in.

Common Mistakes with “At January”

Incorrect: We are planning the event at January. Correct: We are planning the event in January.
Incorrect: I will start working at January. Correct: I will start working in January.
Incorrect: My birthday is at January. Correct: My birthday is in January.

Why Using “At January” Doesn’t Work

Using at January doesn’t work because at is reserved for specific times or precise moments, such as hours or dates. January is a general time period, and in is used to denote months, seasons, and years.

Common Contexts for Time Expressions

Using “In” for Extended Periods

In is ideal when talking about extended periods such as months, years, or centuries. These timeframes are general and broad, so in is the appropriate preposition.

Examples

“He was born in January.”
“We met in 2020.”
“The company was founded in the 21st century.”

Using “On” for Specific Days and Dates

On the other hand, on is used for specific days, like Monday, or specific dates, like the 15th of January.

Examples

“The meeting is on Monday.”
“His birthday is on the 1st of January.”
“We will meet on Christmas Day.”

Using “At” for Precise Times

At is used for specific times, like 5 p.m., noon, or midnight.

Examples

“The flight departs at 3 p.m.”
“We will start at noon.”
“The train arrives at midnight.”

Practical Tips for Avoiding Mistakes

Check for Consistency
