Common questions
How many days is 3 weeks?
Three weeks is 21 days, since 3 × 7 = 21. This is a full calendar count with no remainder, so a stay that starts on a Monday and lasts 3 weeks ends 21 days later on a Monday.
What about half weeks or decimals like 1.5 weeks?
Multiply by 7 the same way. 1.5 weeks × 7 = 10.5 days, and 0.5 weeks is 3.5 days. The half day is real here because a week splits evenly into 7, so fractions carry straight through.
