Colombo is 2.5 hours ahead of Kyiv

Best overlap: 8:00 AM to 4:00 PM in Kyiv is 10:30 AM to 6:30 PM in Colombo.

Kyiv and Colombo overlap from 8:00 AM to 4:00 PM (Kyiv) to the equivalent 10:30 AM to 6:30 PM in Colombo — that's your meeting window. Plenty of room to work with: 8 hours of daily overlap means you can prioritise people's preferences over the clock. One seasonal catch: Kyiv springs forward and falls back, but Colombo doesn't, so the gap changes by an hour for several months of the year.
