FAQ
How do I find out what 9 AM in New York is in London?
Set the Base city to New York and enter the date and 9:00 AM in Base time. The London row shows the local time at that same moment. If the date is different, the row also says Previous day or Next day.
Does it account for daylight saving time?
Yes. Offsets come from the time zone data built into your browser and are worked out for the date you enter, so future dates follow that day’s DST rules. Cities on daylight saving time at that moment show “DST” next to their UTC offset.
What happens on the day the clocks change?
When clocks fall back and a time happens twice, the earlier one is used. When clocks spring forward and you enter a time that never happens, it’s moved one hour later.
My city isn’t in the list.
You can choose from 28 major cities plus UTC. For other places, pick a city in the same time zone. For example, Boston shares New York’s time and San Francisco shares Los Angeles’s.
Will my city list be there next time?
Yes. Your base city and city list are remembered in this browser. The date and time you enter aren’t saved, so the page starts again from the current time.
