# Do layovers count in the 90-in-180 Schengen rule?

Suppose someone on the 90 of 180 rule leaves Schengen on the 90th day.

Then less than 90 days later, they have a flight with one or more layovers in a Schengen country.

Does it get counted if it's the same plane? Change of planes?

What if it is overnight but you don't leave the airport?

How to calculate stays against 90/180 visa rules? relates but doesn't specifically mention layovers. If you don't get off the plane, I presume nobody even looks at your passport. But in one non-Schengen airport, I had to change planes, but first was required to go through passport control, claim luggage, and re-check the luggage.

• Do you need to pass imigration? If you fly from a non-Schengen country to a non-Schengen country, you do not need to pass imigration and you should be alright. But if you travel through two Schengen airports before leaving the area, you need to enter the Schengen zone and do need more days. (But I do not have proof, so I do not write this as an answer.)

• Willeke is correct in that if you don't leave the transit zone and actually enter a Schengen country, then you've not entered and the time doesn't count. However remember that the 90/180 rule is a moving target and the day after you leave the zone the 180 day window keeps sliding forward, so you may actually be able to enter the zone... that's what the calculator is good for.

• You can use schengen 90/180 day calculator: ec.europa.eu/dgs/home-affairs/what-we-do/policies/…. This Schengen manual also will help you. ec.europa.eu/dgs/home-affairs/what-we-do/policies/…

• I am in @Willeke's camp. If a person is admitted to the zone, even for 1 millisecond, it's bookable as a full day against the 90/180 rule. I think it's not really a duplicate of calculating days because that question/answer is vague on the layover/transit corner case. Willeke can choose to add the corner case to the existing canonical, or add an answer here, or dup-vote ect ect. Apr 1, 2016 at 5:28
