Singapore is on the same clock as Hong Kong for most of the year: when it is 10:00 am in Hong Kong it is 10:00 am in Singapore. In offset terms Hong Kong is on UTC+08:00 and Singapore is on UTC+08:00 in January, and UTC+08:00 and UTC+08:00 in July. The converter above works from your browser’s own time zone data, so the figure it shows is the one in force today rather than the one that was in force when this page was written.
Neither city changes its clocks. Hong Kong stays on UTC+08:00 and Singapore stays on UTC+08:00 all year. The two cities therefore keep identical clocks for all of 2026: no conversion is needed, and the only things left to reconcile are the working day, the working week and public holidays.
For arranging anything, the number that matters is the overlap. Hong Kong works 09:00 to 18:00 and Singapore works 09:00 to 18:00, which leaves 09:00 to 18:00 in Hong Kong — 09:00 to 18:00 in Singapore — as the window when both are open. That is 9 hours of shared working time. Both cities work Monday to Friday, so only the clock has to be reconciled.
Two local details worth knowing. The exchange trades 09:30 to 16:00 with a lunch break, and UTC+08:00 has been fixed since daylight saving was dropped in 1979. Singapore is on UTC+08:00 despite sitting almost on the 104th meridian, a legacy of aligning with Malaysia in 1982.
The safest way to write a time for these two cities is to give both, as in "10:00 Hong Kong / 10:00 Singapore", or to give the UTC offset. Abbreviations are the trap: Hong Kong is on HKT for part of the year and HKT for the rest, and the same three letters are reused in other parts of the world for entirely different offsets.
The formula
local Hong Kong- The time you enter, on the Hong Kong clock
offset- Each city’s UTC offset at that moment, read live from the IANA time zone database in your browser
+0- The difference in hours that holds for most of 2026: Singapore is on the same clock as Hong Kong
day shift- Whether the converted time falls on the previous, same or next calendar day in Singapore
How it works, step by step
- Enter a time in Hong Kong using the 24-hour hour box and the minute box — 15:30 is hour 15, minute 30.
- Your browser reports the UTC offset in force in Hong Kong and in Singapore for that moment, so a date near a daylight saving transition is handled correctly rather than with a fixed 0 hour rule.
- The second offset minus the first gives the difference, which is added to the time you entered. A result past midnight is marked as the next or previous day, because that is where most conversion mistakes live.
- The panel also shows the current time in both cities, the date in Singapore, and whether the two offices are open at the same moment.
Worked examples
09:00 in Hong Kong
09:00 in Hong Kong is 09:00 in Singapore — inside Singapore office hours. In 12-hour terms, 9:00 am against 9:00 am. Both offices are open at that moment, so it is a slot either side can accept.
12:00 in Hong Kong
12:00 in Hong Kong is 12:00 in Singapore — inside Singapore office hours. In 12-hour terms, 12:00 pm against 12:00 pm. Both offices are open at that moment, so it is a slot either side can accept.
17:00 in Hong Kong
17:00 in Hong Kong is 17:00 in Singapore — inside Singapore office hours. In 12-hour terms, 5:00 pm against 5:00 pm. Both offices are open at that moment, so it is a slot either side can accept.
Identical clocks, different calendars
Every hour of the day reads the same in Hong Kong and Singapore, so there is nothing to convert. What still differs is the working day — 09:00 to 18:00 in Hong Kong against 09:00 to 18:00 in Singapore — the working week, Mon-Fri against Mon-Fri, and the public holiday calendar, which is where scheduling between these two cities actually goes wrong.
How to read your score
Frequently asked questions
Is there a time difference between Hong Kong and Singapore?
Singapore is on the same clock as Hong Kong for most of 2026, so 09:00 in Hong Kong is 09:00 in Singapore. That holds for the whole year: the two clocks either never change or change on the same dates, as the table on this page shows period by period.
What is 2 pm Hong Kong time in Singapore?
2:00 pm, inside Singapore office hours. In 24-hour form 14:00 in Hong Kong is 14:00 in Singapore, and that is a normal working moment in both cities.
What is the best time to call between Hong Kong and Singapore?
Anywhere between 09:00 and 18:00 Hong Kong time, which is 09:00 to 18:00 in Singapore. Both offices are open across that whole window — 9 hours of it. If you want one answer rather than a range, 13:30 in Hong Kong is the middle of the overlap.
Is Singapore ahead of or behind Hong Kong?
Neither — they keep the same clock. Hong Kong is at UTC+08:00 and Singapore is at UTC+08:00 in mid-January, and UTC+08:00 and UTC+08:00 in mid-July. The clock moves not at all going from Hong Kong to Singapore, which is why either city reaches the end of its working day first.
Do Hong Kong and Singapore change their clocks on the same date?
Neither city changes its clocks. In 2026, Hong Kong does not change its clocks at all, and Singapore does not change its clocks at all. The difference between the two cities therefore holds all year.
What do the abbreviations for Hong Kong mean?
Hong Kong is on HKT in winter and HKT in summer, while Singapore uses +08 and +08. Abbreviations are the least reliable way to write a time: several are ambiguous between regions, and the summer and winter forms are an hour apart. A UTC offset, or the time given in both cities, cannot be misread.
Does this converter stay correct after the clocks change?
Yes. It does not use a stored number for the difference. Each time you change a value it asks your browser for the UTC offset that Asia/Hong_Kong and Asia/Singapore are on at that moment, using the IANA time zone database that ships with your operating system, and takes the difference. The tables on this page are computed from the same database for 2026.
