# Travel Day and Pass Validity
Travel Days are local calendar days inside your Interrail or Eurail Pass's Validity Period; Flexi and Continuous products use them differently.

Also known as: travel day, pass validity, validity period

For both Interrail and Eurail, a **Travel Day** is one local calendar day from 00:00 to 23:59:59 on which the pass can be used. The **Validity Period** is the pass's full window, starting at 00:00 on its selected start date and ending at 23:59:59 on its final date. Travel Days must fall inside that window.
## Why the distinction matters
A pass may remain valid for longer than the number of Travel Days it gives you. With a Flexi Pass, you choose a set number of Travel Days within the fixed Validity Period. With a Continuous Pass, every day in the Validity Period is available as a Travel Day. The exact duration and number of days are product-specific, so a one-month validity window does not automatically mean one month of Travel Days.
On a Travel Day, your pass can cover more than one journey, subject to the pass network and any separate reservation requirements. A Travel Day is a date allocation, not a promise of a seat. For pass and product context, see [Rail Passes](), the [Interrail Global Pass](), and the [Eurail Global Pass]().
## Example
An Interrail 7-days-in-1-month pass starting on 10 January can use its seven Travel Days at any point through 9 February. The pass expires on 10 February. You do not need to use the seven days consecutively, but you cannot use a Travel Day outside the Validity Period.
Calendar months do not all have the same length. For a one-month Interrail or Eurail pass, a 6 February start runs through 5 March in both a non-leap year and a leap year; the leap-year window contains 29 days. A 6 January start runs through 5 February. The selected start date and pass product determine the actual dates.
## Common confusion
Do not confuse a selected start date with the complete Validity Period. The selected start date sets when the window begins, while the Validity Period describes the complete date window that follows. Nor does the word “Travel Day” mean that every train is reservation-free. A pass may still need a separate seat reservation or supplement on a particular service.
Geography is separate from validity. A pass can have a Validity Period and Travel Days while still being limited by its country or network coverage. The [Interrail One Country Pass]() and [Eurail One Country Pass]() provide product context for that distinction.
## Overnight trains and local time
A Travel Day follows local calendar time. On a direct overnight train leaving at 18:10 on 11 August and arriving at 02:15 on 12 August, 11 August counts as the Flexi Travel Day when there is no train change after midnight. The arrival date must still fall within the pass's Validity Period. If you change trains after midnight, the onward journey needs another Travel Day. Time-zone changes use the local time where you are, so midnight is not a single Europe-wide boundary.
Your pass's stated start date, final date, and number of Travel Days determine what you can use. Product or promotion rules may add exceptions; seat reservations and supplements remain separate from pass validity.
## Frequently asked questions
### What is the difference between a Travel Day and a Validity Period?
A Travel Day is one local calendar day from 00:00 to 23:59:59 when your pass can be used. The Validity Period is the complete date window for the pass, from the start date to the final valid date.
### How do Flexi and Continuous Passes use Travel Days?
A Flexi Pass gives you a set number of Travel Days to choose within its Validity Period. A Continuous Pass makes every day in its Validity Period a Travel Day. The exact duration depends on the product.
### How many Travel Days does an overnight train use?
A direct overnight train with no change after midnight generally uses the departure date as the Flexi Travel Day. The arrival date must still be within the Validity Period, and a change after midnight needs another Travel Day.
### Does a Travel Day include a seat reservation?
Not necessarily. A Travel Day determines when your pass day can be used, but a particular train may still require a separate seat reservation or supplement.

- [Flexi vs Continuous Pass]()A Flexi Pass gives you selected Travel Days within a validity period; a Continuous Pass makes every date in that period a Travel Day.
- [Pass Activation]()Pass activation sets up a rail pass for use; it is separate from the validity start date, Flexi Travel Day activation, journeys and required reservations.
- [Seat Reservations]()A reservation secures a seat or sleeping place. It may be compulsory, optional or included with a ticket. With Interrail, the pass is still required.
