PST to EST Time Zone Converter
PST to EST converts US Pacific Time on the West Coast to US Eastern Time on the East Coast. Eastern is 3 hours ahead of Pacific, and because both coasts change their clocks on the same dates, that 3-hour gap holds all year. The converter handles the daylight saving switch for you, so any date you pick is already correct.

Daylight saving is applied automatically for the date you pick. Labels like PST/EST name the zone (Pacific/Eastern); the real abbreviation shifts to PDT/EDT during daylight saving, and gmt here means London (GMT in winter, BST in summer) while utc stays fixed.
The time difference
US Eastern Time is 3 hours ahead of US Pacific Time, every day of the year. To go from a Pacific clock to an Eastern one, add 3 hours. That's it — 8 AM in Seattle is 11 AM in Boston, and 5 PM in San Francisco is 8 PM in Miami.
A worked example
Take 9:00 AM Pacific. On January 15, 2026 that's 12:00 PM Eastern, and on July 15, 2026 it's also 12:00 PM Eastern. The clock result is the same in winter and summer, so noon Eastern holds all year for a 9 AM Pacific start.
Daylight saving & the abbreviation caveat
The slugs read PST and EST — the winter names. From spring to fall both zones shift to daylight time and are really PDT and EDT, which is why locals just say "PT" and "ET." Both coasts switch on the same dates (spring forward March 8, fall back November 1 in 2026), so the 3-hour gap never breaks. The converter picks the right names for whatever date you choose, so the result is never off.
When you'll use it
This is the everyday coast-to-coast conversion: scheduling a call between a West Coast and an East Coast office, catching an East Coast flight departure time, tuning in to a live event or game that starts on Eastern time, or lining up market hours when the New York open is 6:30 AM back in California.
Frequently asked questions
How many hours ahead is EST from PST?
Eastern Time is 3 hours ahead of Pacific Time. When it's 9:00 AM in Los Angeles, it's 12:00 PM in New York. This gap stays the same all year because both coasts start and end daylight saving on the same days.
Does the PST to EST difference change with daylight saving?
No. Both zones spring forward and fall back on the same dates, so the 3-hour gap never moves. The abbreviations change (PST/EST in winter, PDT/EDT in summer), but the difference stays at 3 hours.
What time is 9 AM Pacific in Eastern Time?
12:00 PM Eastern — noon. Add 3 hours to any Pacific clock time to get the Eastern time, on the same calendar day.
