Schengen 90/180 day calculator
This free calculator shows how many of your 90 Schengen days you have used in the 180 days before a chosen date, how many are left, and the last day you can stay on a planned trip.
Add each stay with its entry and exit date, pick the date you want to check (today by default) and optionally a planned entry date and trip length.
The 90/180 rule in plain terms
Visitors who do not need a visa for a short stay, and visitors with a short-stay visa, may stay in the Schengen area for up to 90 days in any 180-day period. The 180-day period is not a fixed block. It is a window that rolls forward one day at a time: for every day you are in the area, you look back over that day and the 179 days before it and count the days you were present.
How the days are counted
Both the day you enter and the day you leave count as full days, even if you spend only an hour in the area. Days spent in Schengen countries are added together across all of them, so 40 days in Slovakia and 50 days in Spain are 90 days, not two separate allowances. Days outside the area, including time in Ireland, Cyprus, the UK or other non-Schengen countries, do not count. This calculator merges overlapping stays so a day is never counted twice.
Reading the result
Days used is the number of days you were present in the 180 days ending on the check date. Days left is 90 minus that figure. The latest-date line assumes you enter on the planned entry date and then stay without leaving, and finds the last day on which your count still stays at 90 or less. Because old days drop out of the window as time passes, a long break lets days free up again.
Who is exempt, and slovakia
Slovakia is part of the Schengen area, so days spent in Slovakia count. Citizens of EU and EEA states and of Switzerland are not subject to the rule. Holders of an EU residence permit or a long-stay (D-type) visa are not subject to it either, and those stays should not be entered. Some countries have bilateral agreements that allow extra time in specific Schengen states for their own citizens, which can change your allowance. If you hold a short-stay visa, also check the validity shown on the visa sticker, which can be shorter than 90 days.
The European Commission publishes an official short-stay calculator at home-affairs.ec.europa.eu (search for "short-stay calculator"). Use it as the reference if border officers might check your dates.
Planning tips
Build in a margin of a few days rather than planning to the last allowed day, because delays, cancelled flights and strikes can push your exit date back. If you travel often, enter every past trip from the last 180 days, including short weekend visits, since each one uses days. Keep boarding passes, tickets or stamps as proof of your dates. If you plan to split time between Schengen and non-Schengen countries, remember that only days spent outside the area free up your allowance, and they free it up gradually as old days leave the rolling window.
Limits of this tool
This is an aid, not legal advice. It does not know your nationality, visa conditions or any bilateral agreement, and it does not store your dates. Overstaying can lead to fines, entry bans and problems with future visas, so keep a margin and keep proof of your entry and exit dates.
Questions
Do entry and exit days count?
Yes. Both are counted as full days in the Schengen area.
Is the 180-day period a calendar half-year?
No. It is a rolling window that ends on the day you check, and it moves with each day.
Does Slovakia count towards my 90 days?
Yes. Slovakia is in Schengen, and all Schengen countries share one allowance.
Do EU citizens need to use this?
No. EU, EEA and Swiss citizens can stay and move freely and are exempt from the 90/180 limit.
What if I need more than 90 days?
Apply for a national long-stay visa or residence permit in the country where you will stay. A short-stay visa cannot be extended beyond 90 days in 180 except in rare cases.
