Frequently Asked Questions
How does the tool know my device's time zone?
It reads your browser's detected time zone using the Intl.DateTimeFormat API and lists it at the top of the dropdown as your device zone, pre-selected by default.
Does the converter account for daylight saving time?
Yes — because it calculates each zone's UTC offset based on the actual date you entered rather than a fixed offset, it correctly reflects daylight saving time rules for that specific date in each region.
Why is one row in the results table highlighted?
The highlighted row shows the same time zone you selected as your source zone, so you can quickly confirm your input against the row for that city.
What if the city I need isn't in the list?
The tool covers 15 major world time zones spanning every UTC offset, plus your own device's zone — if your exact city isn't listed, pick the closest listed city that shares the same time zone.
Is the converted time based on a 12-hour or 24-hour clock?
Results are displayed in 12-hour format with AM/PM, along with the weekday, month, and day, for each time zone in the table.
