Accurately calculate Pacific Daylight Time (UTC-7) to Eastern Standard Time (UTC-5/UTC-4) with instant 3-hour precise time alignment, live clocks, and interactive meeting tools.
Active Zone: ET
Converting Pacific Daylight Time (PDT) to Eastern Standard Time (EST) or Eastern Daylight Time (EDT) is essential for seamless coordination between the US West Coast and East Coast. Eastern Time is exactly 3 hours ahead of Pacific Time when both regions observe synchronized Daylight Saving Time. Because PDT is designated as UTC-7 and EDT as UTC-4, calculating local time in New York, Toronto, or Miami from Los Angeles, San Francisco, or Seattle simply requires adding 3 hours to your local Pacific timestamp.
Whether you are organizing tech product launches between Silicon Valley and Wall Street, scheduling nationwide webinars, planning flight connections, or following national live broadcasts, this reference guide provides exact time conversions, interactive calculator controls, and complete 24-hour reference tables.

Time Difference Mechanics
The physical difference between Pacific Daylight Time (PDT, UTC-7) and Eastern Daylight Time (EDT, UTC-4) is exactly 3 hours. Spanning approximately 45 degrees of longitudinal separation across the continental United States, Pacific Time centers along the 120th meridian west while Eastern Time sits along the 75th meridian west.
PDT operates at UTC-7, while EDT operates at UTC-4. Subtracting offsets: (-4) - (-7) = +3 hours difference.
Both Pacific and Eastern time zones advance clocks by 1 hour on the second Sunday of March (becoming PDT UTC-7 and EDT UTC-4) and fall back on the first Sunday of November. Eastern Time remains 3 hours ahead year-round.
The primary window for cross-country meetings spans 9:00 AM – 2:00 PM PDT, matching 12:00 PM – 5:00 PM EDT on the East Coast (5 hours of shared overlap daily).
Coordinating operations between West Coast technology headquarters and East Coast financial institutions requires strategic schedule management:
Schedule major cross-regional meetings between 10:00 AM PDT (1:00 PM EDT) and 1:00 PM PDT (4:00 PM EDT). This respects West Coast morning arrival schedules while completing calls before East Coast end-of-day.
West Coast investors and traders must account for Wall Street market hours (NYSE & NASDAQ) opening at 9:30 AM EDT, which equates to 6:30 AM PDT locally on the West Coast.
By staffing support teams across both Pacific and Eastern time zones, companies seamlessly deliver 12 hours of active support coverage (8:00 AM EDT to 5:00 PM PDT) without requiring night shifts.
