Find the day on providing the week number

Britta’s parents said they will buy her a puppy on a 2nd week of a month. They selected a puppy but the vet said it will be delivered only based on the token given to them. The token was printed from 1-7 in number representing days of the week.

Britta is very eager and needs to Know the Day on providing the week number [1-7].
