The format of "once a <time unit>" indicates a frequency with which something occurs. "My wife gets her hair done once a month." So used like this, you should say: The dog is given food once a day. We get a day off once a week. You can use "in a week", but it changes the meaning here: We get a day off in a week.

Dec 3, 2017 · I wonder if once a week can be used at the beginning of the sentence and if yes, whether it should be followed with a comma. I tried browsing the Internet and Oxford Advanced Learner's Dictionary, but I haven't found examples with once a week used at the beginning of a sentence. Is the following sentence correct?

Nov 5, 2020 · At least once every week (and less than once every day) The reason for me to add the sentence in the circle brackets is because since I mention "at least" once every week, this mean one or more times every week, which can be equal to once or more every day (so I want to be precise it is less than once every day).

It is perfectly normal for noun phrases to function as adjuncts (or what school grammar bizarrely likes to call "adverb phrases"). It happens all over the place: this week, I'm going; I was paid twice this week, etc. That's what's happening with a week. It's not wrong and it …

Mar 8, 2017 · A game/app developer releasing bug fixes twice a week seems too often to me, so I think once every two weeks is a more reasonable timeline to code things to improve the app. As for the English classes, attending class once every two weeks seems like that is not nearly enough to learn and remember any information from the class.
