What does 1 month continuous mean?

A pass with a validity of 1 month continuous allows you to travel by train daily in a period of 1 calendar month. You can choose to travel every single day in this period, but you don't have to - it's completely up to you.

For example: if you activate your pass on July 10, you are free to travel by train daily from July 10 up to and including August 9.
