How many days in a (leave) week?

Is it 5 working days or 7 days?

My wifes annual leave payslip says

Annual leave acc (wks) 2.21.

This is the first time I've seen it as weeks not days (maybe I'm in the minority)

We are trying to figure out our holiday plans. What does this mean over new years to only apply for the days we need to.
