Tool guide
Choose a date, add participants, and set each person’s city and working hours. The tool uses a UTC timeline and each time zone’s local date and time to find windows when everyone is working.
- Daylight saving time:Built-in IANA time zone rules automatically adjust offsets when the date changes.
- Date rollover:Local times show the previous or next day so early-morning meetings are not misread.
- Privacy:Cities, working hours, and meeting plans are never uploaded.
FAQ
Why does the timeline use UTC?
UTC is a shared reference for everyone. Each cell is then converted to local time, so DST and date changes are not reduced to a fixed offset.
Can working hours cross midnight?
Yes. When the end time is earlier than or equal to the start time, the tool treats it as an overnight shift, such as 22:00 to 06:00.
Is the meeting plan uploaded?
No. Calculations, time zone conversions, and copied content stay in your current browser.
