Thats a good question. I just counted the days for 2017, its 8 and a half. May 1st is half a day off (not for everyone). So 5-6 weeks + 8 days. (Sidenote, most jobs you have to use 3 weeks vacation during summer)

I almost forgot, if you work in the public sector, you also get 2 days of per child under 7 years, for each parent. You can also negotiate to take part of your maternity leave at a later date, some of our friends are now on a 3 month vacation in Australia, using the maternity leave and savings for funding. ( this needs to be negotiated with employer, but its not unusual)

About the same according to a quick Google search.

"It usually adds up to five weeks of vacation plus around nine public holidays (plus other possible company paid holidays or additional vacation time)."
