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.
Does the tool show the current time in each zone live?
Yes — the "Current Time in Each Zone" grid reads the real time from your device and reformats it for every listed zone using the Intl.DateTimeFormat API, refreshing every second without reloading the page.
How does the best meeting time finder work?
Pick two or more zones and a date, and it checks all 24 hours of that day, converting each one into every selected zone's local time with Intl.DateTimeFormat, then highlights the hours that fall within 9 AM-6 PM business hours in every selected zone at once — correctly accounting for daylight saving time on that specific date.
