I wasn't even in Massachusetts then, just one weekend over Labor Day.
(Port Mortuary by P. Cornwell)
context: The narrator's office is in Massachusetts, but she had to stay for work somewhere else for a while.
She regretted that she hadn't been there at her office when she should have.
question: about "over Labor Day"
What I guess is it means: she came back to Massachusetts just one weekend while she was working away from there.
but I couldn't be sure how "weekend" and "Labor Day" are related.
Labor Day must be a part of that weekend, or Labor Days was among that one weekend when she came back.
She stayed during the weekend, and that weekend included Labor Day.
Am I right?
