Kyiv is 6 hours behind Shenzhen
Best overlap: 2:00 PM to 6:00 PM in Shenzhen is 8:00 AM to 12:00 PM in Kyiv.
The overlap falls at 2:00 PM to 6:00 PM in Shenzhen, or 8:00 AM to 12:00 PM if you're in Kyiv. You get roughly 4 hours of shared time, so aim for the middle of that window to keep the call comfortable for both teams. Heads up: because Kyiv changes its clocks and Shenzhen doesn't, the difference moves by an hour twice a year. Confirm the overlap around the DST switch.
