Schengen 90/180 day calculator and worked examples

Use a rolling window

For each day of a proposed stay, look back over the 180-day period ending on that day and count relevant Schengen presence. Include arrival and departure days. It is not 90 days per country or a fixed six-month calendar block, and leaving for a weekend does not reset previous days.

A calendar example with both endpoints counted

Hypothetical example with no earlier Schengen days: arrival on 1 June 2026 and departure on 30 June uses 30 days. Returning on 1 July and leaving on 30 August uses another 61 days: July has 31 days and 1–30 August has 30. The total is 91, so that plan exceeds a 90-day allowance. Leaving on 29 August instead makes the second visit 60 days and the combined total 90, assuming every other entry condition is met.

Map the area correctly

The Council of the EU currently lists 29 Schengen countries. Cyprus is not part of that list; the UK and Ireland are separate too. Separate entry permission still matters outside Schengen. Do not use a nearby destination as an assumed visa-free waiting room or infer its safety and permitted stay from geography.

Use the official calculator before booking

Enter the actual historical entry and exit dates in the European Commission’s short-stay calculator, then test the proposed itinerary using its instructions. Include older visits still within the relevant window. Save the result and supporting travel records. If a past overstay, residence permit, long-stay visa or bilateral arrangement affects your case, ask the relevant authority instead of treating a simple calculator as a legal determination.

Keep permission categories separate

An electronic authorisation does not add visitor days. Long-stay permission is a separate category with its own territorial and activity conditions. EES records border movements; it does not change the ordinary 90/180 limit. Confirm the final itinerary with the responsible authority if the remaining allowance is uncertain.

Why 90 days outside matters in a repeat-trip example

Illustrative dates, assuming ordinary short-stay permission: 1 January to 31 March 2026 uses 90 days. A proposed return on 29 June still has all 90 earlier days in its rolling window; the new entry would be day 91. Returning on 30 June instead lets 1 January fall outside that day’s window. If you then remain continuously, an old day drops out as each new day is added, allowing a 90-day trip through 27 September on this calendar calculation. This example does not resolve any other entry condition.

Use the calculator without hiding older visits

• Add every relevant short stay before the proposed entry, including trips to other Schengen countries. A country change within the area is not a new allowance.
• Enter an ongoing stay with its original entry date and proposed exit date in the proposed-trip fields.
• An overlapping entry in your records does not create two days on the same calendar date; this calculator counts that date once. Resolve inconsistent travel records before relying on the result.
• The result checks each day of the proposed trip, not just the departure day. A compliant final window cannot erase an earlier excess.
• Check the visa’s own validity, permitted duration and entry count separately. A 90-day arithmetic result cannot override a visa allowing fewer days.
