Singapore & Hong Kong Time Difference
🕐 Live Timezone Overlap: Singapore & Hong Kong
Singapore and Hong Kong share the same clock. Both cities run on UTC+8 year-round, which means a 9am start in Singapore lands at exactly 9am in Hong Kong. That alignment is genuinely rare across APAC. The practical result: the full 9am to 6pm working day overlaps completely, giving teams in both cities 9 hours of shared working time. For multinational APAC operations, this is one of the most straightforward city pairings on the continent.
Time Difference: Singapore and Hong Kong
Singapore and Hong Kong share the same UTC offset (+8). If either city observes daylight saving on a different schedule, the offset can shift by an hour during the transition.
Neither Singapore nor Hong Kong observes daylight saving time. Singapore holds UTC+8 permanently, as does Hong Kong. Because neither city shifts its clocks at any point in the year, the time difference between them stays at zero regardless of season. Teams never need to recalculate for spring or autumn changeovers. This stability makes recurring calendar invites reliable indefinitely, with no seasonal corrections required.
Best Times to Meet
With a 9-hour overlap window running 9am to 6pm in both Singapore and Hong Kong, scheduling flexibility is high. That said, a few caveats apply. Hong Kong business culture is highly time-sensitive, with short lunch breaks of around one hour, so back-to-back afternoon slots tend to work well. Singapore hosts many multinational APAC HQs where 9am to 6pm is a firm norm. Inside that 9-hour window, the cleanest slot is typically 10am to 12pm, avoiding the opening hour and staying clear of lunch.

Tips for Scheduling Across Singapore and Hong Kong
- Check both cities' Chinese New Year dates early: Singapore takes 2 days off, Hong Kong takes 3, and the exact dates shift annually.
- Hong Kong lunch breaks run about one hour, so scheduling a meeting at 1pm risks a late start from that side.
- Recurring weekly calls need no seasonal adjustment: Singapore and Hong Kong both hold UTC+8 year-round without any DST shifts.
- Singapore's National Day falls on 9 August and Hong Kong's National Day on 1 October: avoid those dates for critical meetings.
- Morning slots from 10am to 12pm suit both cities, clearing the opening hour while keeping well inside the 9-hour overlap window.
Public Holidays and Working Weeks
Both Singapore and Hong Kong operate a standard Monday to Friday working week, with 9am to 6pm as the canonical working day. The most significant shared holiday is Chinese New Year, which falls in January or February. Singapore observes two public holidays for it; Hong Kong observes three. Singapore also closes for Deepavali and National Day in August, while Hong Kong's second major closure is the Mid-Autumn Festival. Any cross-city meeting plan should check both calendars before confirming dates.
