When California observes Pacific Time (PT), the time zone three hours ahead is Eastern Time (ET)—the standard for the U.S. East Coast, including New York, Washington D.C., and Miami.
| Period | California (PT) | Eastern Time (ET) | Difference |
|---|---|---|---|
| Standard Time (Nov-Mar) | UTC−8 | UTC−5 | 3 hours |
| Daylight Time (Mar-Nov) | UTC−7 | UTC−4 | 3 hours |
The three-hour gap persists year-round because both zones shift simultaneously for daylight saving. Major ET cities: New York, Boston, Atlanta, Toronto, Montreal. Major PT cities: Los Angeles, San Francisco, Seattle, Vancouver.
Practical example: When it's 9:00 AM in Los Angeles, it's 12:00 PM in New York. This consistency simplifies cross-coast scheduling—no seasonal mental math required.
