Schengen days calculator: 4 worked examples

A Schengen days calculator answers one question for any date: how many of your 90 days have you used in the 180 days up to and including that date? The four examples that follow use real 2026 dates, and each one opens in the Schengen calculator with the same stays filled in, so you can check the numbers yourself.

The rule behind every example is the same. Look back 180 days, that day included. Count every day in any Schengen country, with the entry and exit days counted in full. At 90 or fewer on every day of your stay, you're within the standard short-stay rule.

Example 1: days left on a date

You spent March 1 to March 31, 2026 in Schengen (31 days) and May 1 to May 20, 2026 (20 days). How many days do you have left on June 1, 2026?

Step	Result
Window for June 1, 2026	December 4, 2025 to June 1, 2026
Days in Schengen inside the window	31 + 20 = 51
Days left on June 1	90 − 51 = 39

Those 39 days aren't a balance you can spend at any time. The count changes every day. By August 28, 2026, the March days have mostly dropped out and you've used only 50; by September 30, only the 20 May days remain.

Example 2: a trip that goes over partway through

You spent January 10 to February 28, 2026 in Schengen (50 days). You plan to enter again on April 15, 2026 and leave on May 31, 2026. On April 15 you've used only 51 days, so the trip looks fine. It isn't.

Day of the planned trip	Days used in the window
April 15, 2026 (entry)	51
May 24, 2026	90
May 25, 2026	91, over the limit

The trip goes over on May 25. The latest safe exit for a stay entered on April 15 is May 24, 2026: 40 days. This is why a check on the entry date alone isn't enough.

Example 3: how long can I stay from a date?

You have no other Schengen days in the last 180 days, and you enter on June 1, 2026. Your latest safe exit is August 29, 2026, a stay of exactly 90 days. Enter any exit on or before that date and every day of the trip fits.

With earlier stays in the window, the latest safe exit moves earlier, as it did in example 2. The calculator works it out from all the stays you enter.

Example 4: when a full 90 days opens up again

You spent the full 90 days from January 1 to March 31, 2026. When can you start a new 90-day stay?

Not on June 29, 90 days after you left. Days come back one at a time, as each one drops out of the 180-day window. The earliest a new, continuous 90-day stay fits is June 30, 2026: by the last day of that stay, September 27, every day of the earlier stay has left the window.

What the examples leave out

The examples assume you're on an ordinary short stay with no other permission. Stays on a residence permit or a long-stay visa don't count toward the 90 days. If your visa sticker allows fewer than 90 days, that shorter limit applies. The European Commission's short-stay calculator gives the official count, and a border officer has the final say.

How Schengen Calculator helps

The hard part of every example is the list of dates. Schengen Calculator builds that list from the dates and places in your photos, on your iPhone, and lets you add any day by hand. It then runs the same count on every day, so you see your days left without typing a single trip. To try the arithmetic first, the free Schengen calculator runs it in your browser.
