Switzerland permit — absence caps your time outside Switzerland at 179 days in any rolling 365-day period. The statute attaches its consequence at 180 days or more, so 179 is the last safe count. B and C permits lapse after six months abroad unless you file for the stay to be kept alive before you go.
Who it applies to
This matters most if you are:
- A permanent resident who travels often and must protect the status they already hold.
- An applicant counting physical presence toward residence or a passport.
- Anyone who will have to evidence their days to an immigration authority at renewal or application.
The rule — and why it exists
Days outside Switzerland. At most 179 days outside Switzerland in any rolling 365-day period — written as <=179 AWAY / 365.
Why it exists: residence and citizenship are granted to people who actually live in the country. Presence requirements and absence caps are how that is measured rather than asserted.
Counting the days
- On any given day, look back over the 365 days ending on that day (that day included).
- Count every day you were physically outside Switzerland in that span. Partial days count as full days.
- The total must stay at or below 179. Repeat for every day — there is no reset date.
- A day only stops counting once it is more than 365 days old. Leaving and returning changes nothing.
- A day with no record might have been a qualifying day abroad, so the calculator reports unknown days separately and treats the total as a floor, never a guess.

Examples
Example 1 — 118 days recorded abroad in the last 365 days
Stays: United States 2026-01-01 → 2026-04-28. Checked on 2026-12-31.
Result: Days outside Switzerland: 61 of 179 days left (118 used in Switzerland).
Example 2 — 199 days recorded abroad in the last 365 days
Stays: United States 2026-01-01 → 2026-07-18. Checked on 2026-12-31.
Result: Days outside Switzerland: over the limit — 199 of 179 days, first exceeded 2026-06-29.
Exceptions & edge cases
- Absences with permission. Some regimes disregard absences approved in advance or forced by illness; record them and check the source.
- Continuity vs. totals. Some rules require both a total and no single absence over a limit; both must hold.
- Evidence. Authorities may ask for stamps, boarding passes or statements — keep the source of every day.
Common misconceptions
- "Under 179 days means I'm safe." False — other tests can apply, and the count is only one input.
- "It resets when I leave." No. Days age out one at a time, 365 days after they happened.
- "Arrival day doesn't count." Any part of a day inside is a day inside.
