Albania or Montenegro side trip: do those days count?

No. Days spent in Albania, Montenegro, Serbia, North Macedonia, Bosnia and Herzegovina or Kosovo do not use up your Schengen 90 days, because those countries are not in the Schengen area. They do not reset the clock either. The 90 days are counted only on days you spend inside the Schengen countries, across a rolling 180-day window.

This matters for American visitors who string a Dubrovnik or Split holiday together with a few days across the border. Each hop out and back is a Schengen exit and a new Schengen entry, and the Entry/Exit System (EES) records both. ETIAS is not in operation and nobody can apply for it today, so the 90/180 rule and EES are what govern a trip like this now.

Do days in Albania or Montenegro count towards the 90 days in Schengen?

The rule sits in Article 6 of the Schengen Borders Code. It allows stays of no more than 90 days in any 180-day period, “which entails considering the 180-day period preceding each day of stay”, and says the date of entry is the first day of stay on the territory of the Member States and the date of exit the last day. The count is of time on that territory, so a day in a country outside it is simply not a day of stay.

The European Commission says the Schengen area is made up of 29 countries: 25 EU member states plus Iceland, Norway, Switzerland and Liechtenstein. None of the Western Balkan countries above is an EU member or one of those four, so none is on the list.

Does leaving Schengen for a few days reset the 90-day clock?

No. Time away does not wipe anything. It just stops adding days. Your earlier Schengen days stay in the 180-day window until they are more than 180 days old, and then they drop out one by one. The official EU page on the EES says the 90 days in any 180 “is calculated as a single period for all the European countries using the EES”, so a week in Italy, a week in Montenegro and a week in Croatia is two Schengen visits that add together, not three separate allowances.

A worked example (ours, not an official one)

Say you spend 30 days in Italy, cross to Albania for 10 days, then spend 40 days in Croatia, all within 180 days. Counting entry and exit days as days of stay, you have used 70 Schengen days. The 10 Albanian days count for nothing, so 20 Schengen days remain. If you keep going and add more Schengen days, the rolling window still looks back 180 days from each day you are inside.

How does EES record a Balkan side trip?

The EU’s EES page says the system registers non-EU nationals “each time they cross the external borders” of the 29 countries using it. Driving from Croatia into Montenegro, or from Albania into Greece, you leave and re-enter the Schengen area at an external border, so the exit and the new entry are both logged. You can read the day-by-day logic of that in our guide to the second crossing on a return trip.

The EU’s own “Check how long you can stay” tool works from your EES record plus the dates you enter, and asks for your travel document details, but it warns that the result “may vary depending on the actual date of entry and exit” and cannot be read as a decision to grant or refuse entry. It also says it does not reflect any time in the Schengen area that began before 10 April 2026. Our explainer on the tool walks through what its messages mean.

What about each Balkan country’s own rules?

Each of those countries sets its own entry conditions and its own limit on how long a visitor can stay. We have not checked them for this article, so look at the foreign ministry or border police page of the country you plan to visit, or at US government travel advice, before you book. The 90/180 rule discussed here is only the Schengen side of the trip.

What should you do before a multi-country trip?

1. List every date you cross into or out of a Schengen country, including the dips into the Balkans.
2. Add up only the Schengen days, counting entry and exit days, over the 180 days ending on your planned last day.
3. Check your passport meets the Schengen conditions: issued within the previous 10 years and valid for at least three months beyond your planned departure (see the 10-year passport rule).
4. Keep a simple log. If a border officer or the EES record disagrees with you, a dated list of crossings is the first thing to compare.
