24-Hour Overview
Overlap - all zones within 9am-5pm
No overlap found where all 3 zones are within 9am-5pm. Try removing a zone or adjusting expectations.
How the Overlap Calculation Works
Pick the time zones for everyone joining. The tool finds every 30-minute window where every selected zone is between 09:00 and 17:00 local. A freelancer in London (GMT) trying to schedule a Zoom with a client in Mumbai (IST, +5:30) and a partner in Los Angeles (PST, -8) will find that there is no time of day where all three are in standard work hours - one party always has to flex. The visual timeline highlights this with green cells for working hours, amber for early-morning or evening edges, and grey for night.
The next-best windows show themselves quickly once you see the timeline. London-Mumbai overlaps from about 09:30-12:30 GMT (15:00-18:00 IST). London-LA overlaps 17:00-18:00 GMT (09:00-10:00 PST). For all three together, you have to pick whether London takes a late call, LA takes an early call, or India takes an evening call. Rotating which zone takes the unsociable slot is the simplest way to keep distributed teams sane.
Common Multi-Zone Patterns
| Zones involved | Realistic overlap (work hours) | Compromise needed? |
|---|---|---|
| London + Paris | 08:00-16:00 GMT (full) | None |
| London + New York | 13:00-17:00 GMT | None within 9-5 each side |
| London + Mumbai | 09:30-12:30 GMT | Mumbai works late afternoon |
| London + Tokyo | 00:00-08:00 GMT | One side outside work hours |
| London + Sydney | 22:00-07:00 GMT | One side outside work hours |
| UK + India + US East | 13:00-13:30 GMT only | India works late, US works early |
| UK + India + US West | No overlap in 9-5 | One zone always flexes |
Practical Tips for Distributed Teams
Daylight saving is the silent killer. The UK, EU and US all switch on different weekends, meaning recurring meetings drift by an hour 4 times a year. Always confirm the actual local time on the meeting invite in the week after a clock change. Also worth knowing: India, Japan and most of Australia do not observe daylight saving at all, so a recurring call with Mumbai shifts forward an hour every March from a UK perspective and back again in October.
If you are flying internationally for a meeting rather than dialling in, run the [Jet Lag Calculator](/jet-lag-calculator) first - scheduling a 09:00 client meeting on the morning after a London-Tokyo flight is rarely productive for either side. For three-zone calls, a 30-minute slot at 14:00 UK is reachable by Mumbai (19:30) and US East (09:00) but tight for everyone.
Frequently Asked Questions
Does this account for daylight saving time?
The tool uses static UTC offsets (e.g. New York is UTC-5, London is UTC+0). During British Summer Time (late March to late October) London is actually UTC+1, and Eastern Daylight Time shifts New York to UTC-4. For meetings in the next few weeks, double-check using your operating system's time zone settings; for a date 3 months out, the standard offsets are usually right.
What if there is genuinely no overlap?
For UK + Sydney + LA, there is no time when all three are in 9-5. Solutions: split into two calls, switch to asynchronous tools like Loom or a shared doc instead of a meeting, or accept that one zone will always be on a flexed schedule. The timeline flags this when it happens.
Can I save the result?
Not directly. Bookmark the URL with your selected zones (the state is held in the browser, not a database). For recurring meetings, screenshot the timeline as a reference for your team.
Why is the working day set to 9-5?
It is a starting assumption. For teams with different conventions (4-day weeks, 8-4 schedules, evening shifts), use the visual timeline to find your actual overlap rather than relying on the green band. The hour cells are clickable so you can pick any time.
