Best meeting windows
Standard 9 AM – 5 PM hours in UTC and Hong Kong do not overlap. Plan calls for early UTC morning or late UTC evening, and rotate the burden between sides.
Tighter overlap is achievable by having the side with later working hours start earlier, or by treating the first and last hours of each side as flexible. The bar above marks every hour where both cities sit inside a 9 AM – 5 PM window.
About converting UTC time to Hong Kong time
UTC follows the UTC time zone (currently UTC, GMT-0), while Hong Kong follows Asia/Hong_Kong (currently GMT+8, GMT+8). Hong Kong is 8 hours ahead of UTC right now.
Neither city observes daylight saving time, so the offset between them is the same all year.
