◊ common questions

Quick answers. Before you book the call.

What's the time difference between Porto Alegre and Irkutsk?

Porto Alegre is 11 hours ahead of Irkutsk. Porto Alegre runs on GMT-3 and Irkutsk on GMT+8. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.

When's the best time to schedule a meeting?

Standard 09:00–17:00 workdays don't intersect. Most teams compromise with one side meeting early (before 09:00) or late (after 17:00).

Does daylight saving time change the difference?

Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.

How far is Porto Alegre from Irkutsk?
