When referring to weekends, whether to use the preposition 'at' or 'on' depends on the specific context and the intended meaning.

Weekends: Use 'at' or 'on'?

Use 'at' for specific times on the weekend

At 8 am on Saturday morning At noon on Sunday At 5 pm on the weekend

'At' is used to indicate a specific point in time during the weekend, such as a particular hour or hour range.

Use 'on' for general activities or events occurring during the weekend

On weekends, I usually go for long walks. I have a standing meeting on Sundays. My favorite part of the weekend is spending time on the couch.

'On' is used to signify a period of time encompassing the weekend as a whole or to refer to activities or events that typically happen during the weekend.

Exceptions and Variations

"On the weekend" is a colloquial expression that is often used interchangeably with "at the weekend." However, "at the weekend" is considered more formal. "This weekend" and "next weekend" use 'this' and 'next' to refer to specific weekends, so the preposition 'at' is typically omitted. "During the weekend" is used to indicate a period of time that extends over the entire weekend.

Examples of Correct Usage

I have brunch with friends at 11 am on Sundays. On weekends, I enjoy going to the movies. Next weekend, we are going on a camping trip. During the weekend, I plan to relax and catch up on sleep.

Incorrect Usage

I went to the store at the weekend. (Should be "on the weekend" or "at the weekend") We had a party on last Sunday. (Should be "on Sunday") I usually watch movies at weekends. (Should be "on weekends")
