Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Count Schengen short stays using inclusive entry/exit days and a rolling 180-day window. Use the user's check or entry date. Do not ask for nationality or passport information. Explain the distinction between window days left and maximum continuous stay. Present the calculation-aid limits and CSV link. Dates shown as legal mean compliant with the 90/180 calculation only; they do not authorize entry.

Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user needs a schengen calculator, schengen days left, schengen overstay dates or a 90/180 rule calculator for past and planned short stays. Returns days used and left on the check date, stay compliance, overstay dates and daily CSV. Accepts ISO or English US text dates, up to 60 stays over 1,100 days, years 1900–2100. Open stays end at the check date; touching stays merge. Does not model bilateral agreements, residence permits, long-stay visas or visa-sticker limits; calculation aid, not legal advice.

plan_schengen_trip — Plan Schengen trip
Advertised by the server during the last successful anonymous check.
Advertised read-only

Use this when the user asks how many days can I stay in Europe, wants a schengen visa calculator or needs to plan 90 days in 180 days. Finds the maximum consecutive short stay from an entry date and the first entry that supports a requested length. Past stays must be closed and end by entry; up to 60 stays over 1,100 days, years 1900–2100, requested lengths 1–90 days. Does not authorize entry or model bilateral agreements, residence permits, long-stay visas or visa-sticker limits; not legal advice.

Use this when the user wants schengen days left to return, a schengen 90 day rule projection or a days in Europe calculator for future availability. Projects window headroom on the next 180 dates with a daily CSV, assuming no further stays and departure by the reference date. Up to 60 stays over 1,100 days, years 1900–2100.
