✅ Quick Answer: What time is it in another zone?
3:00 PM New York = 8:00 PM London (5-hour gap; 4 hours during the few weeks each spring and autumn when US and UK clock changes do not align). 9:00 AM London = 6:00 PM Tokyo (9-hour gap in winter, 8 hours in summer, since Japan has no daylight saving). 12:00 PM Sydney = 10:00 PM the previous day in New York (14-hour gap).
How it works: pick a date and time, choose your From and To zones, and the converter shows the exact local time — daylight saving handled automatically. All calculations run in your browser; no data is uploaded.
Frequently Asked Questions
How does the time zone converter work?
Pick a date and time, choose your From and To time zones, then click Convert. The converter instantly shows what that exact moment is in the destination time zone, including the correct date.
Are daylight saving time changes handled?
Yes. The converter uses the official IANA time zone database built into your browser, so daylight saving time (DST) is applied automatically for the exact date you choose.
Is my data sent to a server?
No. All conversions happen locally in your browser — nothing you type is uploaded anywhere.
Can I convert the current time right now?
Yes. Click Use current time to fill the converter with the current time in your From zone, and both times update instantly.
Is the time zone converter free?
Yes — completely free with no registration and no usage limits.
What is 3 PM EST in London time?
3:00 PM Eastern Time (New York) is 8:00 PM in London during the standard winter offset (5-hour gap). During the brief spring and autumn transition weeks when the US and UK DST schedules don't align, the gap narrows to 4 hours, making it 7:00 PM London.
How many hours ahead is Tokyo than New York?
Tokyo is 14 hours ahead of New York during the US winter (EST) and 13 hours ahead during the US summer (EDT), because Japan does not observe daylight saving time. So 9:00 AM in New York on a summer day is 10:00 PM the same day in Tokyo.
What time zone is California in?
California uses Pacific Time: UTC−8 in winter (PST) and UTC−7 in summer (PDT). It is 3 hours behind New York, 8 hours behind London, and 17–19 hours behind Sydney depending on the season.
