FAQ
Why do some cells belong to another date?
All rows represent the same instants. A city east or west of the source city may already be on the previous or next calendar date.
Does the comparison use fixed UTC offsets?
No. It uses IANA time zones for the selected date, including daylight-saving rules supported by the browser.
What do the highlighted cells mean?
A highlighted cell marks a local hour from 09:00 through 16:59. It is a visual guide to typical work hours, not a calculation of a person's availability or a meeting recommendation.
