Worked Examples

The 90/180 rule, worked through with real dates.

The rule is easy to state and hard to picture: at most 90 days inside the Schengen Area in any rolling 180-day period. Below are 6 scenarios with actual dates and actual day counts — including the exact day a legal trip becomes an overstay.

Every number here is calculated, not written down.The counts come from the same engine that powers the calculator, so the page cannot disagree with the tool.

Each scenario stands on its own. They are not stages of one journey — every one starts from an empty travel history and lists its own trips, so you can read whichever matches your situation and ignore the rest.

The dates are fixed in 2026 on purpose, so the examples stay quotable. Swap in your own trips to see your own numbers.

Scenario 1 of 6

Two separate trips — how much of the 90 days is left?

The base case. Two ordinary holidays a few months apart, and the count on the day the second one ends.

The trips

Country	Entry	Exit	Days
France	10 Mar 2026	24 Mar 2026	15
Italy	5 Jun 2026	19 Jun 2026	15

The count, day by day

Checked on	Days used	Left	What that means
24 Mar 2026	15	75	Last day of the first trip.
19 Jun 2026	30	60	Last day of the second trip. Both stays are still inside the window, so they add up.

Each row counts the Schengen days inside the 180 days ending on that date.

Takeaway

Each day counts once, and separate trips simply add together while they both sit inside the same 180 days.

Scenario 2 of 6

A stay that is legal on the day you arrive and illegal on the day you leave

Nothing about the entry date is wrong here. The breach appears part-way through, because the total is measured on every single day of the stay — not on the day you booked it.

The trips

Country	Entry	Exit	Days
Spain	5 Jan 2026	20 Feb 2026	47
Germany	1 Apr 2026	20 May 2026	50

The count, day by day

Checked on	Days used	Left	What that means
1 Apr 2026	48	42	Arrival day of the second stay — comfortably inside the limit.
13 May 2026	90	0	Exactly at the limit. Still legal, with nothing left.
14 May 2026	91	0	OverOne more day in the country. This is the first day in breach.
20 May 2026	97	0	OverDeparture day, a week further over.

Each row counts the Schengen days inside the 180 days ending on that date.

Takeaway

A border officer checks the count on the day in front of them. The same trip was fine on arrival, exactly at the limit six weeks later, and in breach the day after that — nothing changed except the date.

Scenario 3 of 6

Does leaving the Schengen Area reset the 90 days?

No — and this is the most expensive misunderstanding of the rule. Time spent outside does not count toward the 90, but the 180-day window keeps rolling the whole time you are away. A short hop out and back does almost nothing.

The trips

Country	Entry	Exit	Days
Netherlands	1 Feb 2026	26 Apr 2026	85
United KingdomDoes not count	27 Apr 2026	4 May 2026	8
Belgium	5 May 2026	6 May 2026	2

The count, day by day

Checked on	Days used	Left	What that means
26 Apr 2026	85	5	The end of the long stay.
4 May 2026	85	5	After a week in the UK. The UK days did not count — but nothing was given back either.
6 May 2026	87	3	Back in Schengen for two days, and now over the limit.

Each row counts the Schengen days inside the 180 days ending on that date.

Takeaway

Going out and coming straight back does not buy days. Days only come back when old stays fall out of the back of the 180-day window, which takes time, not travel.

Scenario 4 of 6

When do the days I already used come back?

One at a time, exactly 180 days after each was spent. Here is a single long stay, watched as it ages out of the window.

The trips

Country	Entry	Exit	Days
Portugal	10 Jan 2026	20 Mar 2026	70

The count, day by day

Checked on	Days used	Left	What that means
20 Mar 2026	70	20	The day the stay ends.
1 Jun 2026	70	20	Ten weeks later. Every day of that stay is still inside the window.
15 Jul 2026	63	27	The earliest days have started dropping off the back.
16 Sept 2026	0	90	180 days after the last day of the stay: the window is clear again.

Each row counts the Schengen days inside the 180 days ending on that date.

Takeaway

The window is a moving 180-day frame, not a yearly allowance. Nothing resets on a date — it drains gradually.

Scenario 5 of 6

How much longer could I stay if I went a month later?

The same travel history and the same question, asked about three arrival dates a few weeks apart. The answer does not improve smoothly — it jumps.

The trips

Country	Entry	Exit	Days
Greece	15 Feb 2026	5 May 2026	80

Arriving on different dates

If you arrive	Already used	You could stay
1 Aug 2026	80	10 days
20 Aug 2026	73	90 days
1 Sept 2026	61	90 days

Takeaway

Nineteen days of waiting turns a ten-day trip into a full ninety-day one. The gain is not proportional to the wait, so the useful question is never "how many days do I have now" but "what does this look like if I leave a fortnight later".

Scenario 6 of 6

I used all 90 days. When can I go back, and for how long?

A stay that runs the allowance down to zero, and the exact date the door opens again. The answer surprises most people: it is not another ninety days away, and the return trip is not a short one.

The trips

Country	Entry	Exit	Days
Austria	1 Mar 2026	29 May 2026	90

The count, day by day

Checked on	Days used	Left	What that means
29 May 2026	90	0	The 90th day — the allowance is spent.

Each row counts the Schengen days inside the 180 days ending on that date.

Earliest possible return

28 Aug 2026

89 days are still on the clock that morning, and yet the stay could run 90 days — the old stay expires at the same pace the new one builds up.

Takeaway

You are not locked out for another ninety days. The window has already drained enough by late August to let you back in — and because the old stay keeps expiring at exactly the rate the new one accumulates, the return trip can run the full ninety days without ever crossing the line.

Run these numbers on your own trips

The calculator does exactly what this page does — enter your entry and exit dates and it shows the count for any day, the latest date you must leave, and the earliest you can return.
