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.
7 p.m. rule
The 7 p.m. rule allows you to count only 1 travel day instead of 2 when travelling overnight. This is how it works: if you travel on a train (or multiple trains) that departs after 19:00 (7 p.m.) and arrives at its final stop after 04:00 (4 a.m.), you only need to enter the arrival date in the travel calendar, even if you leave the train before 4 a.m. This way you get 5 hours of travel for free. More about the 7 p.m. rule.
The ÖBB Nightjet between Rome and Munich/Vienna, leaving at 18:58, is also included in the 7 p.m. rule.
The Hungarian Raiways night train between Budapest-Keleti and Split, leaving at 18:53, is also included in the 7 p.m. rule.
Let us give you an example...
Say that your night train departs on a Monday at 19:15 and arrives at its final destination Tuesday at 10:00. You leave the train at 03:00 on Tuesday morning. In this case, you only need to use one travel day – the day of your arrival. You can continue using your Interrail Pass until the end of that travel day (in this case Tuesday, 23:59).
