A travel day is a 24-hour period in which you can travel on trains with your Interrail Pass. It lasts from 00:00 (midnight) to 23:59 on the same calendar day. On each travel day, you have access to the train networks where your Interrail Pass is valid.

For mobile Passes a travel day lasts from 00:00 (midnight) to 23:59 Central European Time (CET). Please note that some European countries do not observe CET. Finland, Estonia, Latvia, Lithuania, Romania, Bulgaria and Greece are all one hour ahead (CET+1). This means there can be a difference in the start and end time of a travel day when compared to your local time while travelling.

When travelling on a night train that leaves on one day and arrives the next, you only have to spend 1 travel day: the day of departure
