Time Difference Between Japan and USA
Japan Standard Time (JST) is 9 hours ahead of Pacific Standard Time (PST) and 12 hours ahead of Eastern Standard Time (EST). During daylight saving time in the US, the time difference changes to 8 hours between JST and Pacific Daylight Time (PDT) and 11 hours between JST and Eastern Daylight Time (EDT).
Note: Japan does not observe daylight saving time, so the time difference remains constant throughout the year.
Daylight Saving Time Considerations
Daylight saving time (DST) affects the time difference between Japan and the USA. In the US:
- Daylight saving time begins on the second Sunday in March and ends on the first Sunday in November
- During DST, US time zones are one hour ahead of standard time
- This calculator automatically adjusts for DST when converting times
For example, if it's 10:00 AM JST on a date when the US is on DST, the equivalent time in Pacific Time would be 1:00 AM (PDT) and in Eastern Time would be 4:00 AM (EDT).
Example Conversions
Here are some example conversions to help you understand how the time difference works:
| Japan Time (JST) | Pacific Time (PST/PDT) | Eastern Time (EST/EDT) |
|---|---|---|
| 9:00 AM (Standard Time) | 12:00 AM (PST) | 3:00 AM (EST) |
| 3:00 PM (Standard Time) | 6:00 PM (PST) | 9:00 PM (EST) |
| 11:00 PM (Standard Time) | 2:00 AM (PDT) | 5:00 AM (EDT) |
These examples show the time difference during standard time. During daylight saving time, subtract one hour from the Pacific and Eastern times shown.
