Compare cities, working hours and daylight-saving changes on one interactive timeline. TimeBridge scores every possible slot for comfort and fairness, so the same person is not always the one dialling in at midnight.
Timezone maths runs in your browser using real IANA rules.
Drag the highlighted block, or use the arrow keys, to move the meeting.
Most timezone tools answer “what time is it there?”. The harder question is which time is reasonable to ask of everybody — and that depends on hours, days, flexibility and who has taken the awkward slot last time.
Every city gets its own band on one shared time axis, so a vertical line through the mesh is genuinely the same instant everywhere. Day, evening and night are washed in behind, with sunrise and sunset worked out locally from coordinates.
Open the converter →Set working hours, preferred meeting hours and how far outside them each person will stretch. Where everyone lines up, a corridor lights up across every row — and where only some do, it says exactly how many.
See the overlap →The best slot is not the biggest overlap. TimeBridge scores comfort for each person, then weighs the worst-off participant and how evenly the inconvenience is spread — so 09:00 for one and 23:00 for another never wins.
Rank meeting times →Offsets are calculated from real IANA rules for the exact date in view. When the gap between two cities is about to change, you are told the date it changes and what it changes to — and clock times that happen twice, or never, are named rather than guessed.
Check the clock changes →Download an ICS file, open the event prefilled in Google Calendar or Outlook, copy a tidy summary for chat, save a PNG card, or send a link that carries the whole plan inside it. Every one of those is generated in your browser.
Create an event →No account, no calendar connection, no meeting database, no AI. City search runs against a bundled dataset, so even what you type stays on your device. Nothing about a meeting is stored once you close the tab.
Read the privacy note →Add a few cities and see where the day actually overlaps. Nothing to sign up for.
