Do airport transit and travel days count toward the Schengen 90/180 limit?
Staying airside in a Schengen airport's international transit zone, without clearing passport control, does not count toward your 90/180 limit. But every day you actually enter the Schengen Area counts as a full day — including your arrival day and your departure day — even if you're only passing through or there for a few hours. More →
Does the Schengen 90-day clock reset when I leave the area or enter a different country?
No. The Schengen 90/180-day limit uses a rolling 180-day window, so the clock never "resets" — not when you leave the area and not when you move between Schengen countries. The 90-day allowance is shared across all 29 Schengen states, and days only free up as old days drop out of the back of the 180-day window. More →
Is the Schengen Area the same as the European Union?
No. The Schengen Area is a passport-free travel zone, while the European Union is a political and economic union, and their memberships only overlap. As of 2025 the Schengen Area has 29 countries: 25 EU members plus 4 non-EU countries (Iceland, Norway, Switzerland, and Liechtenstein). Two EU members, Ireland and Cyprus, are not full Schengen participants. More →
What counts as a "day" for tax-residency day counts?
There is no single global definition: what counts as a "day" depends on the rule. For the Schengen 90/180 rule, both your arrival day and your exit day count as full days. For most tax-residency tests (such as the US, New York, and Canada), any part of a day spent in the country or state generally counts as a whole day, though some rules instead look at where you were at midnight. Always check the specific authority, because the threshold, the reference period, and the counting method all differ. More →
Can I be a tax resident of two countries at the same time?
Yes. Each country sets its own residency test, so you can qualify as a tax resident of two (or more) countries in the same period. When that happens and the two countries have a tax treaty, "tie-breaker" rules usually assign you to just one of them for treaty purposes — but you should confirm with a tax adviser or the relevant tax authorities.

What happens if I overstay the Schengen 90/180 limit?
Overstaying the Schengen 90/180 limit is an immigration violation that can lead to a fine, a removal order, and an entry ban of up to five years that applies across the entire Schengen Area, not just the country you were in. Penalties and how strictly they are enforced vary by country and by your circumstances, so even a one-day overstay should be avoided and any uncertainty checked with the relevant national authority.

Is the 183-day rule measured over a calendar year or a tax year?
It depends on the jurisdiction — there is no single "183-day rule." Canada counts days in a calendar year, the UK uses its tax year (6 April–5 April), New York uses your taxable year, the US substantial presence test blends three calendar years with a weighted formula, and Schengen ignores years entirely in favour of a rolling 180-day window. Always confirm the reference period with the specific tax or border authority that applies to you. More →
Do both my arrival and departure days count as full days?
Usually yes. Under the Schengen 90/180 rule and most tax day-counts (including the US substantial presence test and Canada's 183-day sojourner rule), any day you set foot in the country counts as a full day, so both your arrival and departure days count, no matter the time of day. The main exception is the UK Statutory Residence Test, which generally counts a day only if you are in the UK at midnight, so your departure day usually does not count. More →
