Add the cities in the room
Each row is a city, and each city carries its own working hours. Nine to six means nine to six on that city's clock — not on yours.

Pikkola lines up every city in your meeting, compares their working hours, and ranks the hours that actually work — for a date you choose, with that date's daylight-saving rules.

Method
Each row is a city, and each city carries its own working hours. Nine to six means nine to six on that city's clock — not on yours.
Green is inside working hours, amber is early or late, grey is the middle of the night. Hover a column to compare all cities at the same instant.
Every hour of the date is scored against everyone's working day. The top three windows come with a copyable summary, a calendar file and a link your team can open.
With Seoul, London and New York in one call, the working days barely touch: London sits between the two, and the only shared hour lands at the edge of somebody's evening. The answer is usually not the middle of the day — it is the hour with the fewest people outside their working window, and it moves twice a year when daylight saving changes. Pikkola calculates each date from the time zone database, so November's meeting is not planned with June's offsets.
Questions
The good hour is the one inside everyone's working day, not the one most convenient for the largest group. Pikkola scores every hour of the chosen date against each participant's working hours and ranks the windows where the fewest people fall outside nine to six.
Yes. Offsets are calculated in your browser from the IANA time zone database for the exact date you pick, so a meeting in November uses November's rules instead of today's offset.
No. The page works the moment it loads. Nothing is saved to an account because there are no accounts.
Cities, working hours and the selected slot are processed in your browser and kept in local storage so the page remembers your setup. Nothing is sent to a server, and no analytics or third-party scripts run here. Sharing is opt-in: the link you copy carries the meeting details.
Copy a plain-text summary with every city's local time, download a calendar file with the event already in UTC, or copy a Pikkola link that reopens the same plan for whoever opens it.
