Schengen 90/180 Calculator

The Rolling 90-in-180 Calculation

The rule is not a fixed six-month block. For every presence day, count that day and the 179 calendar days immediately before it. The total cannot exceed 90 under the general short-stay rule. This calculator converts dates to UTC calendar-day ordinals, expands each completed stay with both endpoints included, and counts only presence that falls inside each moving window.

Days Remaining at Entry vs. Longest Continuous Stay

Days remaining on a proposed entry date subtract the prior presence still visible in that date's rolling window from 90. The longest continuous stay is tested one future day at a time. Older stays can roll out as the proposed trip advances, so a traveller may be able to stay longer than the simple remaining number shown on the first day. The calculator displays both values to keep that distinction explicit.

Entry and Exit Dates Are Inclusive

The entry date counts as the first day and the exit date as the last day. January 1 through January 30 is therefore 30 days, not 29. Two stays cannot share a calendar day in this input: if an exit and re-entry occur on the same date, combine them into one interval so the shared day is counted once.

How Earliest Re-Entry Is Found

Starting on the proposed date, the calculator moves forward until a candidate day plus recorded presence in its inclusive backward-looking 180-day window totals no more than 90. The result answers when at least one general-rule day is available. It does not promise that a full 90-day trip begins then; use the separate continuous-stay output for that question.

Visa, Permit, EES, and Bilateral Exceptions

A short-stay visa can authorize fewer days than the general maximum. Residence permits and long-stay visas use different treatment. Bilateral agreements, nationality, EES data, missing stamps or records, and state-specific practice can also require a different analysis. Those facts are outside this date-only planner and should be checked with official sources or qualified advice.

Official Rule Review — August 13, 2026

The calculation and exclusions were reviewed against the European Commission's current short-stay calculator page and user manual, the current consolidated Schengen Borders Code on EUR-Lex, and current Commission EES guidance. The public calculator covers 29 Schengen countries and excludes Cyprus and Ireland; the EES has been fully operational across the Schengen area since April 10, 2026. Future legal or system changes should trigger a new source review before embedded guidance is updated.

Frequently Asked Questions

How does the Schengen 90/180-day rule work?

For each day you are present, look backward over that day and the preceding 179 calendar days. Your total presence in that rolling 180-day window generally cannot exceed 90 days. Because the window moves every day, older travel can drop out while a new stay continues; the days remaining at entry can therefore differ from the longest continuous stay available from that date.

Do entry and exit days both count as Schengen days?

Yes. Under the Schengen Borders Code, the date of entry is the first day of stay and the date of exit is the last day, so both are counted. A same-day visit counts as one day. If you exit and re-enter on the same calendar day, record one combined interval so that day is not counted twice.

When can I re-enter the Schengen area after using 90 days?

It depends on the exact pattern of the previous stays. This calculator scans forward from the proposed date and identifies the first date when that day plus recorded presence in its backward-looking 180-day window is no more than 90. An uninterrupted absence of 90 days can support a new stay of up to 90 days under the general rule, but shorter absences may release days sooner.

Does a Schengen visa always allow 90 days?

No. A visa can authorize fewer than 90 days or impose a narrower validity period or number of entries. The European Commission says not to use its general short-stay calculator when the visa allows less than 90 days. Follow the visa sticker, applicable official guidance, and any authority decision.

Do residence-permit or long-stay-visa days count in this calculator?

No. The general Commission calculation excludes periods authorized under a residence permit or long-stay visa. The EES has been fully operational across Schengen countries since April 10, 2026, but this tool cannot read EES data or decide how mixed statuses, bilateral arrangements, nationality-specific rules, or discrepancies in official records affect an individual case.

Is this result official permission to enter?

No. It is a planning estimate from the dates entered. The European Commission's own calculator is also a supporting tool rather than a legal entitlement. Border and immigration authorities decide from official records, the applicable law, visa or permit terms, and the traveller's complete circumstances.
