If you're a tourist with a passport from a visa-exempt country (US, UK, Canada, Australia, most of South America and East Asia), you can stay in the Schengen Area for **up to 90 days in any rolling 180-day window**, total, across all member countries combined.

The Schengen Area is the world's largest borderless travel zone. Once you enter any of its member states, internal border checks mostly disappear. The 90/180 rule is the headline number, but the details, which days count, when the window resets, what an "overstay" actually triggers, are where travelers trip up.

## Which countries are in the Schengen Area?

As of 2026, **29 countries** are full members:

Austria · Belgium · Bulgaria · Croatia · Czech Republic · Denmark · Estonia · Finland · France · Germany · Greece · Hungary · Iceland · Italy · Latvia · Liechtenstein · Lithuania · Luxembourg · Malta · Netherlands · Norway · Poland · Portugal · Romania · Slovakia · Slovenia · Spain · Sweden · Switzerland

**Not in Schengen** (commonly mistaken): Ireland, Cyprus, the UK, and most of the Balkans.

## How the 90/180 rule works

Look back from any given day. In the past 180 days, you cannot have spent more than 90 days inside the Schengen Area, total.

It is **rolling**, not calendar-based. The window slides forward every day. A trip that "expired" 181 days ago no longer counts.

It is also **cumulative across all member countries**. Three weeks in Portugal plus two weeks in Greece is five weeks against your 90 days, they aren't separate budgets.

## What counts as a day?

For Schengen purposes:

- **Your arrival day counts** as a full day inside the area.
- **Your departure day counts** as a full day inside the area.
- A two-night trip arriving Friday and leaving Sunday counts as three days.
- Transit through a Schengen airport with passport control (e.g. a layover where you clear immigration) counts.

## The most common mistakes

1. **Treating 90 days as a calendar-quarter allowance.** It isn't. A heavy spring can lock you out of a summer trip.
2. **Forgetting that arrival + departure both count.**
3. **Assuming country borders reset the count.** They don't.
4. **Losing track of past trips** and overstaying by a few days, which can trigger a multi-year re-entry ban.

## Manual tracking vs. automatic

You can do the math by hand with the [official EU Schengen calculator](https://travel-europe.europa.eu/eu-short-stay-visa-calculator_en), or with a spreadsheet, or with DaysAbroad (which does it automatically from your phone's location).

The headline trade: manual tracking is free but error-prone, especially after a few trips. Tools exist to remove the error.
