Best time to meet
No shared working hours.
Central Daylight Time and Hanoi 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.

- Does this account for daylight saving time?
- Yes. We track every clock change in both places, so the abbreviations you see — CDT and +07:00 — 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.
