Quick answer
What “90 days in any 180 days” means
The rule uses a rolling 180-day look-back period. On each day of your stay, count the days spent in the relevant area during the previous 180 days. Your total cannot exceed 90.
Simple example
If you spend 60 days travelling in participating Schengen countries, you have 30 days remaining within the relevant rolling 180-day window. Leaving for a few days does not automatically reset the count.
The limit is shared across Schengen countries
For Schengen countries, the 90 days are not a separate allowance for France, Spain, Italy or Germany. Time across those countries is counted together.
Cyprus is a special case
The official ETIAS FAQ states that stays in Cyprus are calculated separately from the 90/180-day allowance used for the other ETIAS countries.
ETIAS authorisation validity and permitted length of stay are different concepts. A valid three-year ETIAS never means a three-year stay.
Frequently asked questions
Does leaving Schengen reset the 90 days?
No. The calculation is based on a rolling 180-day window.
Can I spend 90 days in France and then 90 days in Spain?
Not under the normal Schengen short-stay calculation: time in participating Schengen countries is combined.
Does Cyprus count in the same 90-day total?
The official ETIAS FAQ says Cyprus is calculated separately.
