Expert writing Tips
Best practice
Consider using "within a week" or "in a week" when focusing on completion or occurrence before the end of the week, instead of emphasizing the duration.
Common error
Avoid using "a week's time" when you actually mean "weekly" or "every week". "A week's time" refers to a specific period, while "weekly" indicates a recurring event.
