What time is it in Honolulu when it's 9:00 AM in London?
Type 9:00 into the London field above and the converter shows the matching Honolulu time for today, daylight saving included. It also shows the Honolulu date in case the time crosses midnight.
Does this converter handle daylight saving between London and Honolulu?
Yes. It uses your browser's own time-zone data (Europe/London for London, Pacific/Honolulu for Honolulu), which carries each region's daylight-saving rules, so the result stays correct all year.
Can it convert Honolulu time to London time as well?
Yes — press the swap button and the converter flips to show Honolulu → London, with the same live clocks and time picker.
