Prepositions of Time

“You can come over on the weekend.”
You can visit sometime during the weekend, maybe just for a short time.
“You can come over for the weekend.”
You can visit and stay for the whole weekend, usually including at least one overnight stay.
We meet at New Year’s (around the holiday time)
The party is on New Year’s Eve (Dec 31 night)
We relax on New Year’s Day (Jan 1)
We usually travel at Christmas. (the general period around Christmas)
We have dinner on Christmas Day.
We open presents on Christmas Eve.
I stay home on Boxing Day.
As a good general rule, when the holiday name includes “Day” like Canada Day, Marine Day, or Sports Day, we use on because it refers to a specific day.
For holidays without “Day” in the name, like Halloween, Thanksgiving, or Christmas, it’s common to use at when talking about the holiday period or celebration.
‘Long weekends’ usually happen when a public holiday falls on a Friday or Monday, giving people a three-day weekend.
For example: July 19, July 20 and July 21 (Marine Day) was a long weekend.
