Italy's time zone: CET, CEST and the dates

Italy keeps Central European Time, UTC+1, from the last Sunday of October to the last Sunday of March, and Central European Summer Time, UTC+2, in between.

The changeover dates for 2026, 2027 and 2028

Summer time runs March 29 to October 25 in 2026, March 28 to October 31 in 2027, and March 26 to October 29 in 2028. In spring the clock moves at 01:00 UTC, when 02:00 becomes 03:00 in Italy; in autumn it moves back at 01:00 UTC, when 03:00 becomes 02:00.

Those dates are calculated from the rule, the last Sunday of March and the last Sunday of October, and not read from an official calendar: the Commission's ten-year table was not retrievable. The arithmetic is deterministic, and it is still worth confirming for a date you are booking against.

Why this matters for a timed ticket

A slot at 8:30 am in Rome is 08:30 in Rome, and the moment a batch of tickets goes on sale 30 days earlier is on Italian clocks too. Convert from your own UTC offset for that specific date, not from the difference you remember from last summer.

The trap is real, because Italy and North America do not change clocks on the same weekend. For a few weeks in spring and autumn the usual gap between Rome and New York is one hour different from what you expect, which is enough to miss a release. See the Colosseum release mechanics for what that costs.

The rule, and the reform that never happened

Directive 2000/84/EC, in force since 2001, fixes summer time across the EU from the last Sunday of March to the last Sunday of October. The Commission proposed ending the twice-yearly change on September 12, 2018, and the European Parliament supported it on March 26, 2019, but the Council never took a final position.

So the rule stands. If that ever changes, this page changes with it; the fact underneath carries a validity to March 31, 2027 for exactly that reason.

17 states on CET, and the two neighbors that differ

17 EU member states keep CET, which is why crossing from Italy into France, Austria or Slovenia does not move your watch. Ireland and Portugal use WET, one hour behind; Bulgaria, Cyprus, Estonia, Finland, Greece, Latvia, Lithuania and Romania use EET, one hour ahead.

That count of 17 comes from a single Commission page. It should be rechecked if any member state changes its zone.

Reading Italian clocks on the ground

Timetables, tickets and museum signs in Italy use the 24-hour clock: 18:15 is 6:15 pm, 21:00 is 9:00 pm, 00:30 is half past midnight. Station boards do the same, and so does the small print on a museum door.

The one place it bites is the evening cutoff. A last entry of 17:30 is 5:30 pm, not 7:30 pm, and it is the most expensive misreading a traveler makes in an afternoon.
