Calculating the live gap…
Two Asian financial capitals, one identical clock
Hong Kong and Singapore keep the exact same time year-round. Both fix their clocks at UTC+8 with no seasonal adjustment, so a 10:00 a.m. meeting in one city is a 10:00 a.m. meeting in the other, with no conversion, no mismatch windows, and no exceptions.
Rivals and partners at once
Hong Kong and Singapore are frequently compared as competing regional headquarters for banks, funds, and multinational corporations expanding into Asia — both offer English-language business environments, deep capital markets, and similar time zones relative to European and North American counterparts. Firms that maintain offices in both cities benefit from the identical clock: teams can coordinate throughout the working day without any time-zone planning at all.

Because neither city has ever practiced daylight saving time, Hong Kong and Singapore are one of the few pairings covered here whose relationship truly never changes — not seasonally, not briefly, not ever, as long as both keep their current standard time.

Every row from 9:00 a.m. to 5:00 p.m. is highlighted — Hong Kong and Singapore share a full working-day overlap, just like New York and Toronto.
How we calculate this page: both live clocks, the current gap, the DST transition dates, and the hour-by-hour overlap table are all computed directly from the IANA Asia/Hong_Kong and Asia/Singapore time zone data via your browser on every page load — nothing here is a fixed, hard-coded figure.
