How it works
This calculator shows you the date that was exactly 180 days before any reference date. Pick a date (today by default) and the answer appears.
Why 180 days matters: the Schengen 90/180-day rule uses a rolling 180-day window. From any date, you look back 180 days and count every Schengen day inside that span. Days outside that 180-day span do not count toward your 90-day allowance.
So the date 180 days before your reference point is the start of your rolling window on that date. Trips that ended before this date no longer count. Trips that started after it count in full. Trips that overlap the boundary count only from the start of the window onwards.
The calculation is plain calendar arithmetic: 180 calendar days, including weekends and public holidays. There is no business-days exception and no rounding by month. The Schengen Borders Code specifies exactly 180 days, not six months, because months vary in length.
If you want this 180-day window combined with your past trips, the Days Remaining calculator does that automatically. This tool is for working backwards from a specific date.
