No, there’s some confusion here. There are two distinct benefits you are entitled to when you become a father.

One is that you get exactly 1 week of paid leave.

The other is the right to take 26 weeks of unpaid ‘parental leave’ during the first 9 years, which is often used to e.g. start working 4 days a week (the leave is used at a rate of 1 day per week then; you could also use it for taking half a year off at once).
