Best time to meet
No shared working hours.

Vostok Time and Pacific Time are too far apart for a working-day overlap. The least-unsociable option is an early-morning call on one side and an evening one on the other — or hand work off asynchronously and let the planet do the waiting.

What is the time difference between Vostok Time and Pacific Time?
Vostok Time is 12 hours ahead of Pacific Time right now. We always show the live, daylight-saving-correct difference, so this figure already accounts for whichever side is observing summer time today.
When it's 10am in Vostok Time, what time is it in Pacific Time?

What's the best time for a call between Vostok Time and Pacific Time?
There's no comfortable 9-to-5 overlap between Vostok Time and Pacific Time — they sit on opposite sides of the planet's working day. Plan for an early or late call on one side, or hand work off asynchronously.
Does this account for daylight saving time?
Yes. We track every clock change in both places, so the abbreviations you see — +05:00 and PDT — are the ones actually in effect right now, not a fixed all-year value. When either side changes its clocks, this page updates automatically.
Why is the date sometimes different on each side?
When two places are far enough apart, the same moment can fall on different calendar days. That is why some conversions are marked "previous day" or "next day" — it is the same instant in time, read off two clocks that crossed midnight at different points.
