When will ETIAS start, and does it change the 90/180 rule?

ETIAS is not a visa and it does not extend a permitted stay. The EU's official ETIAS site says the system is scheduled to start operations in the final quarter of 2026 and that the specific date will be announced before launch. Check that source again close to travel, because an operational date is subject to change.

Keep the two questions separate

An ETIAS authorisation concerns whether an eligible visa-exempt traveller may travel. The 90/180 rule concerns the length of an ordinary short stay. They answer different questions, so one does not substitute for the other.

An authorisation does not add days to a stay limit, and a clear day count does not confirm that you meet every ETIAS or entry requirement. A traveller can need to manage both once ETIAS starts. Passport status, visa requirements and the purpose of travel can remain relevant as well.

For the ordinary short-stay count, start with the Schengen 90/180 rule. For a current eligibility or launch question, use the EU's official ETIAS guidance rather than relying on an old travel article.

Plan with the current information

The practical sequence is to check the official ETIAS status, confirm the documents and conditions that apply to you, then review the stays that affect your planned date. Do that before making a time-sensitive booking where a change in the rule or your itinerary would matter.

If your travel history is incomplete, correct it before treating a day count as useful. Photo-based suggestions can help recall a trip, but a suggested stay is still something to check against your own records. Entry documents and official travel advice remain more important than an app result.

How Flags helps

Flags: Schengen Calculator is for the day-counting side: it helps record stays and plan a trip against a rolling window. It does not apply for ETIAS, check an application, or replace official travel advice. Review and correct the history before you use it to plan.

Check the official ETIAS source before travel because dates and requirements can change. Flags is a tool, not legal advice — the border officer has the final say.
