Why this matters for stored times
A clock change is the reason a future appointment should never be stored as an offset. Save
"2027-03-14 09:00 at Europe/Rome" and it resolves correctly whatever the rules
turn out to be. Save "2027-03-14 09:00 UTC+02:00" and you have
frozen today's rules into a date that may fall on the other side of a transition — or of a
change to the rules themselves.
Frequently asked questions
Does Bologna change its clocks?
Yes. Bologna observes daylight saving time, moving between UTC+1 (CET) and UTC+2 (CEST). Under the rules currently published, the next 10 years contain 20 changes, all listed on this page.
When do the clocks next change in Bologna?
March 29, 2026 — clocks go forward 1 hour, from 02:00 CET to 03:00 CEST. Because the change is defined in Bologna's own local time, it happens at that reading regardless of what other countries are doing that weekend.
What happens to the hour that is skipped or repeated?
When the clocks go forward, the local times inside the gap never occur — so a meeting set for one of them has no instant to happen at. When they go back, the hour before the change repeats, so that local reading occurs twice, an hour apart. Our time zone converter flags both cases instead of silently picking one.
How far ahead can these dates be trusted?
They come from the IANA time zone database, which is what browsers and operating systems use, and they reflect the rules published today. Governments occasionally change or abolish daylight saving with only weeks of notice; when that happens the database is updated and this page is regenerated from it on the next build.
