How long can I stay in Italy without a visa?

90 days within any rolling 180-day period. The clock is Schengen-wide: days in Italy, Spain, Germany and 25 other countries all draw on the same 90. It's a rolling window, not a calendar reset, so if you spent 60 days in Europe last spring you may have less than 90 available now. Border officers do check, and overstaying can mean fines or an entry ban. For a normal two- or three-week holiday this is simply not an issue — it matters for snowbirds, remote workers, and anyone doing back-to-back European trips.
