Karachi is 3 hours behind Hong Kong for most of the year: when it is 10:00 am in Hong Kong it is 7:00 am in Karachi. In offset terms Hong Kong is on UTC+08:00 and Karachi is on UTC+05:00 in January, and UTC+08:00 and UTC+05:00 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 Karachi stays on UTC+05:00 all year. The difference is therefore fixed for all of 2026, which makes this one of the few city pairs where a single number is the whole answer: Karachi is always 3 hours behind Hong Kong. Recurring meetings between the two never drift, and the table below confirms it period by period.
For arranging anything, the number that matters is the overlap. Hong Kong works 09:00 to 18:00 and Karachi works 09:00 to 17:00, which leaves 12:00 to 18:00 in Hong Kong — 09:00 to 15:00 in Karachi — as the window when both are open. That is 6 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. Pakistan keeps UTC+05:00 all year, half an hour behind India, which is the usual source of confusion on regional calls.
Write the invitation in both clocks. "10:00 Hong Kong / 07:00 Karachi" removes the ambiguity that abbreviations introduce — Hong Kong alone is read as HKT in winter and HKT in summer, and calendar software will happily convert one into the other without telling you.
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
−3- The difference in hours that holds for most of 2026: Karachi is 3 hours behind Hong Kong
day shift- Whether the converted time falls on the previous, same or next calendar day in Karachi
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 Karachi for that moment, so a date near a daylight saving transition is handled correctly rather than with a fixed 3 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 Karachi, and whether the two offices are open at the same moment.
Worked examples
09:00 in Hong Kong
09:00 in Hong Kong is 06:00 in Karachi — before the working day starts in Karachi. In 12-hour terms, 9:00 am against 6:00 am. Only one of the two offices is open at that moment, so it is worth offering rather than assuming.
12:00 in Hong Kong
12:00 in Hong Kong is 09:00 in Karachi — inside Karachi office hours. In 12-hour terms, 12:00 pm against 9:00 am. 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 14:00 in Karachi — inside Karachi office hours. In 12-hour terms, 5:00 pm against 2:00 pm. Both offices are open at that moment, so it is a slot either side can accept.
23:00 in Hong Kong, and the date problem
23:00 in Hong Kong is 20:00 in Karachi on the same day. This is where conversions go wrong in writing: the time is right, the day is not, and a meeting invitation sent for "Tuesday" arrives for the wrong Tuesday. Give the date in both cities whenever the converted time is near midnight.
How to read your score
Frequently asked questions
How many hours behind Hong Kong is Karachi?
Karachi is 3 hours behind Hong Kong for most of 2026, so 09:00 in Hong Kong is 06:00 in Karachi. That difference holds for the whole year, because the two clocks either never change or change on the same dates — the table on this page confirms it period by period.
What is 2 pm Hong Kong time in Karachi?
11:00 am, inside Karachi office hours. In 24-hour form 14:00 in Hong Kong is 11:00 in Karachi, and that is a normal working moment in both cities.
What is the best time to call between Hong Kong and Karachi?
Anywhere between 12:00 and 18:00 Hong Kong time, which is 09:00 to 15:00 in Karachi. Both offices are open across that whole window — 6 hours of it. If you want one answer rather than a range, 15:00 in Hong Kong is the middle of the overlap.
Is Karachi ahead of or behind Hong Kong?
Karachi is behind. Hong Kong is at UTC+08:00 and Karachi is at UTC+05:00 in mid-January, and UTC+08:00 and UTC+05:00 in mid-July. The clock moves back going from Hong Kong to Karachi, which is why Hong Kong reaches the end of its working day first.
Do Hong Kong and Karachi change their clocks on the same date?
Neither city changes its clocks. In 2026, Hong Kong does not change its clocks at all, and Karachi 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 Karachi uses PKT and PKT. 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/Karachi 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.
