Frequently Asked Questions
How is daylight saving time handled?
The page uses your browser's Intl API to calculate DST-aware offsets for each city. If a city is currently observing DST, the displayed time and UTC offset reflect that automatically.
Can I change the base city?
Go back to the World Timezone Map, click on a different city's popup, and select "View time differences" to open this list with that city as the base.
What do the green and red time colors mean?
Green indicates the city is within typical business hours (8:00-17:00 local time). Red indicates it is outside business hours.
