Understanding PST to EST Conversion
Time Zone Basics
Pacific Standard Time (PST) is 3 hours behind Eastern Standard Time (EST). When it's 4:00 PM in Los Angeles (PST), it's already 7:00 PM in New York (EST).
Daylight Saving Time
Both PST and EST observe Daylight Saving Time, becoming PDT and EDT respectively. The 3-hour difference remains constant throughout the year.
Geographic Coverage
PST covers the west coast of the United States including California, Washington, and parts of Oregon. EST covers the eastern seaboard including New York, Florida, and parts of eastern Canada.
Business Implications
When scheduling meetings between PST and EST, remember that a 4:00 PM PST meeting would be at 7:00 PM EST, potentially outside of standard business hours for east coast participants.
