Schengen Calculator guides

Every Schengen Calculator guide, grouped by topic, with the rules and the sources behind each answer.

The Schengen 90/180 rule, explained
A source-backed explanation of the EU short-stay rule, its rolling window, and the limits of a day-counting app.
- What counts as a day in the Schengen 90/180 rule?
  Entry and exit days normally count in full for the 90/180 calculation; check official guidance for visas and edge cases.
- ETIAS status: what changes and when
  ETIAS has not started and has no confirmed start date. It is a travel authorisation, not a visa, and it does not change the 90/180-day limit.
- What does a Schengen calculator do?
  What a Schengen calculator can help you count, what it cannot decide, and how to keep a usable travel record.
- Is a Schengen visa calculator the same as a 90/180 calculator?
  A clear distinction between counting a short stay and checking the conditions written on a visa or other travel document.
- How many Schengen days do I have left?
  A practical way to work out remaining Schengen days without treating a rough total as border permission.
- Does leaving Schengen reset the 90 days?
  Why leaving the area does not create a fresh 90-day allowance, and how the rolling reference period works.
- Which countries are in the Schengen Area?
  The current Schengen-country list and why a trip across several member countries uses one shared short-stay calculation.
- Is there a Schengen calculator app that tracks your days automatically?
  Most Schengen day-counters make you type every trip or track your location. Flags reads the dates already in your photos — on-device, no GPS, nothing uploaded — and shows days used out of 90.
- What happens if I overstay the Schengen 90 days?
  A Schengen overstay can mean a fine, a deportation note on your record, or an entry ban of up to several years — and how badly it goes depends largely on the officer.
- When can I re-enter Schengen after hitting 90 days?
  When you can re-enter Schengen isn't a fixed wait — your days come back one at a time as old ones expire from the rolling 180-day window. Here's how to find the earliest date.
- How are multiple-entry Schengen days counted?
  A multiple-entry permit lets you cross the border as often as you like, but every day inside Schengen still counts toward the same rolling 90 — here is how the totals add up.
- Why a spreadsheet fails for tracking Schengen days
  A Schengen spreadsheet looks tidy but breaks on the one thing that matters — the rolling 180-day window. Where it goes wrong, and what to use instead.
