# AI告诉免签旅行者（美国、英国、加拿大）离开申根区一天（例如去伦敦或摩洛哥）会重置他们的90天计时

## 根因

申根90/180天规则计算在180天滚动窗口内在申根区停留的所有天数；短期离开不会重置计时——只有连续离开90天以上才能重新开始计数。

## 解决方案

1. ```
   Use the EU's Short-Stay Visa Calculator (https://ec.europa.eu/assets/home/visa-calculator/calculator.html) to track your days. Ensure total days in Schengen within any 180-day window do not exceed 90.
   ```
2. ```
   If you need to stay longer, apply for a national long-stay visa (D visa) from a Schengen country before traveling, which allows stays beyond 90 days.
   ```
3. ```
   Plan your travel so that you spend at least 90 consecutive days outside Schengen before re-entering for a fresh 90-day period.
   ```

## 无效尝试

- **** — Assuming that a day trip to London resets the 90-day counter; the days spent in Schengen before and after the trip are still counted in the 180-day window. (75% 失败率)
- **** — Believing that leaving to a non-Schengen country (e.g., Morocco, Switzerland) for a weekend resets the clock; Switzerland is part of Schengen, and any non-Schengen exit only pauses the count, does not reset. (80% 失败率)
- **** — Thinking that the 90-day limit applies per country; it applies to the entire Schengen area collectively. (90% 失败率)
