What is a travel day?
A travel day lasts 24 hours from midnight to midnight. On each travel day you have access to the train networks where your Interrail Pass is valid.
There are 2 types of Interrail Passes with a different number of travel days. The right pass for you depends on how much time you expect to spend travelling by train during your European trip.
Travel days with a flexi pass
If you have a flexi pass , e.g. a Global Pass 5 days within 15 days, you can hop on and off trains on any 5 travel days within a period of 15 days. For example, if your pass is valid from 1 June - 15 June, you can choose any 5 days during this period to travel by train. Travel days do not have to be consecutive and you decide during your trip when you use them.
You must enter the date of each travel day in the travel calendar on your pass before boarding the first train, free bus or free ferry of each day.
Travel days with a continuous pass
If you have a continuous pass, e.g. Global Pass 22 days continuous, you have 22 travel days and can take advantage of train travel during each of these days. For example, if your pass is valid from 1 September to 22 September, you can travel by train on each of these days.
With the continuous pass you don't need to fill in the dates on which you travel.
