Meeting planner across time zones

 
 

The meeting planner takes several places at once and shows a grid of local times side by side, so you can see which hours are inside the working day for everyone rather than working out each conversion separately and hoping. It is built for the case a converter handles badly: three or more locations, where every candidate slot is unsociable for at least one of them.

From the UK the geography is unusually favourable and worth exploiting. London mornings overlap comfortably with continental Europe, the Middle East and India; London afternoons overlap with the east coast of the United States, and late afternoons with the west. Roughly 2.00 pm to 5.00 pm UK time is the widest window that reaches both Europe and North America inside normal hours. Asia-Pacific is the hard direction — Sydney is nine to eleven hours ahead depending on the season, which leaves the UK early morning as the only civil option.

Two things to check before sending an invitation. Clock changes fall on different dates in different countries, so a slot that works in October may be an hour out in November for one participant and not for another. And a slot that is fine on the clock may still be a closed day: bank holidays differ between England and Wales, Scotland and Northern Ireland, so a Monday that is clear in Manchester may be a holiday in Edinburgh or Belfast.
