เครื่องคำนวณเชงเก้น 90/180 วัน

The Schengen Days Calculator tracks how many days you have spent and how many remain under the 90/180-day rule governing short-stay visits to the Schengen Area. The rule states that non-EU nationals from visa-exempt or short-stay visa countries may stay for a maximum of 90 days within any rolling 180-day period. This is not a fixed calendar period — the 180-day window slides forward each day, which makes manual tracking surprisingly difficult and error-prone. The Schengen Area is a zone of 29 European countries that have abolished passport and border controls at their mutual borders, creating a single external border for travel purposes. All days spent anywhere within the Schengen zone count against the same 90-day allowance — there is no separate counter for each country. A traveler who spends 30 days in France, 30 days in Germany, and 30 days in Spain has used all 90 days, even though they visited three different sovereign nations. The consequences of overstaying the 90/180 limit can be severe and far-reaching. Penalties vary by country but commonly include fines ranging from a few hundred to several thousand euros, deportation at the traveler's expense, and entry bans of one to five years recorded in the Schengen Information System (SIS). An overstay record affects future visa applications not just for Schengen countries but potentially for other destinations that check immigration compliance history, including the United States, United Kingdom, Canada, and Australia. This calculator is essential for frequent business travelers, digital nomads, retirees splitting time between Europe and other regions, and anyone planning multiple trips to Europe within a year. By entering all Schengen entry and exit dates, the calculator determines exactly how many days have been consumed in the current 180-day window, how many remain, and when previously used days will expire and become available again — enabling precise trip planning that avoids accidental overstays.

1. 1Step 1 — Enter All Schengen Travel Dates: Input every trip to the Schengen Area as a pair of entry and exit dates. Accuracy is critical — both the day you enter and the day you leave count as days of presence. If you traveled to multiple Schengen countries on one trip without leaving the zone, it counts as one continuous stay. Include all trips from at least the past 180 days to ensure the calculation is complete.
2. 2Step 2 — Set the Reference Date: Choose the date for which you want to calculate your status. For checking current compliance, use today's date. For planning a future trip, use your intended entry date. The calculator will look back exactly 180 days from this reference date to determine which previous stays fall within the counting window.
3. 3Step 3 — Calculate the 180-Day Window: The calculator determines the window start date by subtracting 179 days from the reference date (the window includes both the start and reference dates, totaling 180 days). Only stays that fall partially or entirely within this window are counted. Stays that ended before the window start date are irrelevant and do not consume any days.
4. 4Step 4 — Count Days Present Within the Window: For each trip that overlaps with the 180-day window, the calculator counts every day of presence. If a trip started before the window and ended within it, only the days from the window start onward are counted. Entry and exit dates both count as days present. Transit days where you passed through immigration and entered the Schengen zone also count, even if you only spent a few hours.
5. 5Step 5 — Calculate Remaining Allowance: Days Remaining equals 90 minus the total Days Used. If the result is positive, you can still spend that many additional days in the Schengen zone on or after the reference date. If the result is zero, you have no remaining allowance and must not enter or remain. A negative result indicates an overstay has occurred or would occur.
6. 6Step 6 — Determine When Days Expire: As the 180-day window rolls forward, older stays eventually fall outside it. The calculator identifies exactly when each previously counted day will expire, showing when additional allowance becomes available. For example, if you spent 10 days in January, those 10 days will stop counting 180 days after each day, gradually freeing up allowance.
7. 7Step 7 — Plan Future Trips: Using the remaining allowance and day expiration schedule, you can plan future trips to maximize time in Europe without overstaying. The calculator shows the maximum length of stay for a trip starting on a given date, and when a full 90-day allowance will next be available. This is particularly useful for digital nomads and frequent travelers who alternate between Schengen and non-Schengen countries.
