This PST to EST converter turns any time in Pacific Standard Time (PST) into Eastern Standard Time (EST), using your device clock so daylight saving is applied automatically. EST is 3 hours ahead of PST. PST is UTC−8 (PDT: UTC−7); EST is UTC−5 (EDT: UTC−4).
PST covers Los Angeles, San Francisco, Seattle; EST covers New York, Toronto, Miami. Because both zones change their clocks on different dates, the difference is not constant through the year. The tables below show both cases, and the converter at the top always uses the rule in force on the date you pick.

Frequently asked questions
What is the time difference between PST and EST?
EST is 3 hours ahead of PST. That comes from the UTC offsets: PST is UTC−8 and EST is UTC−5. For example, 9 am PST = 12 pm EST.
Is EST ahead of or behind PST?
EST is 3 hours ahead of PST, so when it is noon in PST it is 3 pm in EST. Ahead means the clock there already shows a later time; a call at 5 pm PST lands at 8 pm EST.
Does PST or EST observe daylight saving time in 2026?
PST switches to PDT (UTC−7) on March 8 and back on November 1 in 2026. EST switches to EDT (UTC−4) on March 8 and back on November 1. Between those dates the difference in the table above shifts by an hour, which is the usual cause of missed calls in spring and autumn.
What is the best time for a meeting between PST and EST?
Standard office hours (9 am to 5 pm) overlap from 9 am to 2 pm PST, which is 12 pm to 5 pm EST. Pick a slot inside that window and both sides stay within a normal working day. Check the daylight saving dates above, because the window moves by an hour when only one side has changed clocks.
Which cities use PST and EST?
PST (Pacific Standard Time) is used in Los Angeles, San Francisco, Seattle, Vancouver. EST (Eastern Standard Time) is used in New York, Toronto, Miami, Atlanta. Some cities inside a zone skip daylight saving, noted in parentheses, so their offset matches only part of the year.
