About the Time Zone Meeting Planner
With 9:00 to 17:00 working hours, New York and London overlap for 3 hours on January 14, 2026: 09:00 to 12:00 in New York, 14:00 to 17:00 in London. The planner applies the same local hours in every city unless you give a city its own, uses each zone's offset on the date you pick, and lists every window in which all the cities are inside their hours at once. With a meeting length chosen it drops shorter windows, marks the longest as Suggested, and writes invite text or an .ics file for it. A 24-hour strip shows the same hours as shaded bars, one row per city, with the overlap outlined.

The first city is the reference zone, and the date is read there. In March 2026 the US clocks change on March 8 and the UK clocks later in the month, so for those weeks New York is 4 hours behind London instead of 5.
Frequently asked questions
- When do New York and London working hours overlap?
- With 9:00 to 17:00 in both, 09:00 to 12:00 New York time, 14:00 to 17:00 in London: 3 hours on January 14, 2026. On March 9, 2026, after the US clocks have changed and before the UK clocks do, the overlap is 4 hours, 09:00 to 13:00 in New York.
- How does the meeting planner handle daylight saving time?
- It uses each zone's offset on the date you pick, from your browser's time-zone database. A reference time that does not exist moves forward by the gap: 02:30 on March 8, 2026 in New York becomes 03:30, and the page says so. A time that happens twice, such as 01:30 on November 1, 2026 in New York, uses the earlier one.
- Can I plan across time zones for an overnight shift?
- Yes. An end hour earlier than the start runs past midnight: 22 to 6 in London and Paris on October 14, 2026 gives two windows, London 00:00 to 05:00 (Paris 01:00 to 06:00) and London 22:00 to 24:00 (Paris 23:00 to 01:00 the next day), 7 hours in all.
- Why is there no overlap between Los Angeles and Tokyo?
- With 9:00 to 17:00 in both there is little room. On December 2, 2026 the planner finds 1 hour, 16:00 to 17:00 in Los Angeles, 09:00 to 10:00 the next day in Tokyo; on July 8, 2026, with Los Angeles on summer time, there is none, and the page names Tokyo as the city with no hours in common.
- Does it skip weekends and holidays?
- No. Weekends, public holidays and lunch breaks are not modelled: the same hours apply to every day. A Friday afternoon slot in Los Angeles, such as 16:00 on December 4, 2026, is a Saturday morning in Tokyo, and the planner still lists it.
- How many cities can I compare, and can I share the plan?
- A reference city plus up to 7 others. Copy Link writes ref, time, bizStart, bizEnd and cities into the address, plus length and hours when you set them, and opening it restores the plan; nothing is saved in the browser. A value the planner cannot use is named in an Ignored from the link note. Copy invite text gives one line per city, such as London: 14:00 to 15:00 (UTC+0) for a 1-hour call from 09:00 in New York, and Download .ics saves the same slot as a calendar file.
