◊ common questions

Quick answers. Before you book the call.

What's the time difference between Honolulu and Rome?

Honolulu is 12 hours ahead of Rome. Honolulu runs on GMT-10 and Rome on GMT+2. The gap can shift by an hour when either side enters or leaves daylight saving — the live clocks above always reflect the current offset.

When's the best time to schedule a meeting?

Standard 09:00–17:00 workdays don't intersect. Most teams compromise with one side meeting early (before 09:00) or late (after 17:00).

Does daylight saving time change the difference?

Yes, if either city observes DST. When one side shifts and the other doesn't, the gap changes by one hour. The DST badges under each clock show whether each zone is currently shifted and when the next transition lands.

How far is Honolulu from Rome?

About 12,916 km as the crow flies (great-circle distance). A non-stop commercial flight cruises that in roughly 15h 42m, not counting airport time, winds, or routing around restricted airspace.

Can I send this meeting time as a calendar invite?

Yes. Pick a time on the slider above, open the meeting card, customize the title and duration, then download the .ics file. It imports cleanly into Google Calendar, Outlook, and Apple Calendar with the correct timezone attached.
