Welcome to the forum, jcbphil!Which is grammatically correct: Mondays to Sundays or Monday to Sunday?. Such phrase will be used to refer to a repeated cycle of events. please help
Not where I live.Would "open Mondays through Fridays" ("s" included) be correct, when related to a place which is open every week from Monday to Friday?
In US English if you are always open you can say "We are open seven days a week" or "open daily".
The usual phrase is "Monday THROUGH Saturday" rather than "TO", which I have never seen.
In that case you would be open on Monday, Saturday, and all the days between.
