How the Calculator Works

Understand how each section helps you track your Schengen compliance and plan your trips.

The 90/180 Day Rule

The Schengen Area allows non-EU visitors to stay for up to 90 days within any 180-day period. This is a rolling window, not a fixed period.

How the rolling window works:

  • For any given day, look back 180 days from that date
  • The 180-day window is inclusive of both start and end dates (e.g., from today, the window starts 179 days ago, giving you 180 total days including today)
  • Count all days spent in the Schengen Area during those 180 days
  • If the total is 90 days or less, you are compliant
  • The window "rolls" forward each day, dropping old days and adding new ones
Reference Date

The Reference Date is the anchor point for calculating your 180-day window. By default, it's set to today's date, but you can change it to any date.

Why adjust the reference date?

  • Check your compliance status on a future date
  • See when past stays will "roll off" the 180-day window
  • Plan when you'll have more days available
Current Status

Shows your compliance status based on the reference date you've selected. The 180-day window is calculated backward from the reference date.

Compliant

You have 90 days or fewer used in the window and can continue your stay or plan trips.

Nearing Limit

You're approaching the 90-day limit. Plan carefully to avoid overstaying.

Over Limit

You have exceeded 90 days in the 180-day window. You should not be in the Schengen Area.

Recorded Stays

Track all your past and current stays in the Schengen Area. Each stay records your entry and exit dates.

Note: Both entry and exit days count as days used. If you enter on January 1 and exit on January 3, that's 3 days used.

Check Proposed Trip

Plan future trips and see if they comply with the 90/180 rule before you book. The calculator checks every day of your proposed trip against the rolling 180-day window.

What it checks:

  • Days already used from recorded stays
  • Days from other saved proposed trips
  • Days from the trip you're checking
  • Whether any day during the trip would exceed 90 days
