PST to EST Converter

What this does

Enter a time on the US West Coast and read the matching East Coast time. The left side is the IANA zone America/Los_Angeles and the right is America/New_York, so the answer follows the daylight-saving rule that was genuinely in force on the date you picked rather than a hardcoded three-hour shift. It all runs in the page, so it keeps working with the network off and nothing you type is sent anywhere.

Is Eastern always exactly three hours ahead of Pacific?

Almost always. The two coasts change their clocks on the same dates — forward on the second Sunday in March, back on the first Sunday in November — so they travel together: PST (UTC−8) alongside EST (UTC−5) in winter, PDT (UTC−7) alongside EDT (UTC−4) in summer. Three hours either way. The gap breaks only on the changeover mornings themselves, because each zone flips at 2:00 AM local time. In March, Eastern springs forward three hours before Pacific does, so from 11:00 PM Pacific on the Saturday until 2:00 AM Pacific on the Sunday the coasts sit four hours apart rather than three.

What is 9am PST in EST?

Noon. Nine in the morning in San Francisco is 12:00 PM in New York. The rest of a normal working day lines up like this:

How do I convert a Pacific time to Eastern here?

Three steps, and the result updates as you type:

1. Set the date, not just the time — the date decides which pair of abbreviations applies, and in March and November it is what separates one season's offset from the other.
2. Type the Pacific wall-clock time on the left, or press Use now to load the current Pacific clock.
3. Read the Eastern equivalent on the right. The line underneath states the gap that applies at that exact instant.

Does "PST" still mean anything in summer?

Not literally. From the second Sunday in March to the first Sunday in November the West Coast is on PDT, and the accurate catch-all is "Pacific Time" or "PT". Nearly everyone still writes PST year-round anyway, and so do calendar invites. This page converts using the Pacific zone itself, so it answers what you meant regardless of which abbreviation you typed.

When should I schedule a coast-to-coast call?

The honest overlap is five hours wide: 9:00 AM to 2:00 PM Pacific, which is 12:00 PM to 5:00 PM Eastern. Earlier than 9:00 AM Pacific and you are asking the West Coast to start before its day does; later than 2:00 PM Pacific and the East Coast is already wrapping up. It also means an "end of day Eastern" deadline lands at 2:00 PM where you are sitting. For the opposite direction see EST to PST, for several zones side by side use the timezone converter, and for counting business days to a deadline see working days.
