Time in Olsztyn, Poland

Time zone: CEST (UTC/GMT +02:00) — Europe/Warsaw

Clocks in Olsztyn are set to CEST, 2 hours ahead of UTC (UTC+02:00). Software that asks for a region wants Europe/Warsaw — the IANA identifier for this zone.

One date to watch: Sunday, 25 October 2026. That is when Olsztyn goes back 1 hour onto CET — recurring meetings set before then will land an hour out unless the calendar handles zones properly.

Population: about 171,803 — 18th largest of the 41 Poland cities indexed here.

Current gap between Olsztyn and cities people most often need to coordinate with. These figures already account for daylight saving where it applies.

Assuming a 09:00–17:00 day at both ends, these windows (in Olsztyn local time) fall inside working hours for both cities.

No shared working window exists with Los Angeles or Sydney, so those calls have to sit outside somebody's normal hours.

Same zone, same time — each of these sits on Europe/Warsaw alongside Olsztyn, including through any clock change.
