Meeting Time Finder Across Time Zones
Most planners line up clocks and leave the judgement to you. This one asks each person when they actually work, scores every half-hour slot by how many people it costs, and tells you which participant is paying for the compromise. It also checks whether the slot survives the next daylight-saving change.
What "unsociable" means here
Each slot is scored per person: inside their stated working hours counts fully, within one hour of either edge counts as a stretch, and anything further out counts as nothing. A slot that is merely legal for everyone loses to a slot that is comfortable for everyone, and the table says which is which rather than collapsing it into one number.
Daylight saving is the failure mode worth naming
A recurring meeting agreed in one season quietly moves for part of the group when a daylight-saving transition arrives — and the two hemispheres do not transition together, so a slot can shift twice a year in opposite directions. For the slot you pick, this tool scans the next year in each participant's zone and reports the date of the first repeat that lands at a different local time for them, before you send the invitation rather than after someone misses it. That date is the first affected meeting, which is not always the clock-change date: a meeting early enough in the day can still fall on the old offset on the changeover date itself.
What this assumes
- Time zone rules come from your browser's IANA database. They are correct as of your browser's last update; governments change the rules with little notice, and no tool can know a change that has not been announced.
- Working hours are the same on the chosen date for each person. Part-time patterns, split shifts, and public holidays are not modelled — a slot this tool likes can still land on someone's day off.
- Half-hour granularity. Meetings that start at :15 are not considered.
