Time Zone Converter
Time Zone Converter: Convert the Time Between Any Cities
A time zone converter turns a time in one place into the matching time somewhere else. Pick a date and a time, choose the zone you are starting from, and add as many destinations as you need. This free time zone converter shows each result with its date, the UTC offset, the time difference and whether it falls in business hours, so scheduling a call across continents becomes quick. It follows the daylight saving rules of every zone for the date you choose, and you can switch between a 12-hour and a 24-hour clock.
Quick answer: 10:00 AM in New York on October 6, 2026 is 11:00 PM in Tokyo on the same day. New York is on daylight saving time (UTC−4) and Tokyo is at UTC+9, so Tokyo is 13 hours ahead.
How Time Zone Conversion Works
Every time zone is defined by its offset from UTC, Coordinated Universal Time. To convert, you move the time back to UTC and forward to the destination.
For a source of 10:00 AM in New York at UTC−4 and a destination of Tokyo at UTC+9, the calculation is 10:00 + 4 hours gives 14:00 UTC, and 14:00 + 9 hours gives 23:00, or 11:00 PM.
Daylight Saving Time
Many countries move their clocks forward in spring and back in autumn, but not on the same days, and many zones never change. That is why the time difference between two cities can shift by an hour during the year. This converter looks up the offset for the exact date, so it stays correct even in the weeks when one country has changed its clocks and another has not.
| Zone | Standard time | Daylight saving time |
|---|---|---|
| New York | UTC−5 | UTC−4 |
| Los Angeles | UTC−8 | UTC−7 |
| London | UTC+0 | UTC+1 |
| Paris and Berlin | UTC+1 | UTC+2 |
| Dubai | UTC+4 | No change |
| Islamabad and Karachi | UTC+5 | No change |
| Delhi and Mumbai | UTC+5:30 | No change |
| Singapore | UTC+8 | No change |
| Tokyo | UTC+9 | No change |
| Sydney | UTC+10 | UTC+11 |
| Auckland | UTC+12 | UTC+13 |

Tips for Scheduling Across Time Zones
Look for the overlap in business hours, which the converter marks for each place. State the time zone in invitations, such as 3:00 PM London time, and avoid relying on abbreviations alone, because some are shared by several zones. When a meeting is close to a daylight saving change, check the date again. For counting days or hours around a deadline, the time calculator, hours calculator and days between dates calculator can help.
Limits of This Converter
The converter relies on the time zone data in your browser, which follows the standard IANA database. Governments sometimes change their rules at short notice, so very recent or future changes may not be reflected on an old device. A zone with only a few places listed here is represented by a major city that shares its rules.
