This page opens the time zone converter with Los Angeles as the start zone and New York added to the cards. Pick a date and a time and each card shows the time there with its UTC offset.
The Eastern cities are 3 hours ahead of the Pacific ones all year, so 9:00 AM in Los Angeles is 12:00 noon in New York. Both zones change their clocks on the same dates, which keeps the gap at 3 hours. In summer they are called PDT and EDT, and the gap is the same.
How to convert time between time zones
- Enter the date, the time and the zone that time is in.
- Add the cities or zones you want to compare.
- Read each local time, then the strips for shared working hours.
Questions
Is the gap ever 2 or 4 hours?
Not between these two zones. They change their clocks on the same dates, so the gap stays at 3 hours. Check a date in March or November to see both cards move together.
Which day is it in New York for a late evening call?
From 9:00 PM Pacific on, it is already the next day in New York. The New York card then shows +1 day beside the time.
How do I convert a time to another time zone?
Find each zone’s UTC offset on that date, then add or subtract the difference. London is UTC+1 in summer, so 09:00 in London is 08:00 UTC, which is 17:00 in Tokyo (UTC+9).
Why do UTC offsets change during the year?
Many places move their clocks for daylight saving time, so their offset from UTC changes twice a year. Check the date you are converting, not only today’s offset.
Why does a zone show +1 day?
The converted time falls on a different calendar date in that zone, so it is the next day (+1) or the previous day (−1). Late evening in New York is often the next morning in Tokyo.
What do the working-hour strips show?
Each strip follows the starting zone’s day, hour by hour. Shaded cells are 09:00 to 17:00 in that row’s zone, so you can see where the working hours of several zones overlap. On a clock-change day, an hour that does not exist (such as 02:00 when clocks go forward) is left as an empty outline.
