How to convert PST to EST

To convert PST to EST, add 3 hours all year. For example, when it is 12:00 noon in Pacific Time (Los Angeles) it is 3:00 PM in Eastern Time (New York) in winter. In the converter above the source and target zones are already selected: enter a date and a time and the result appears at once.

The two zones

Pacific Time covers Los Angeles, San Francisco, Seattle, Las Vegas and Vancouver. It is Pacific Standard Time (PST, UTC−8) in winter and Pacific Daylight Time (PDT, UTC−7) in summer, often written simply as PT.

Eastern Time covers New York, Washington, Miami, Atlanta, Boston and Toronto. It is Eastern Standard Time (EST, UTC−5) in winter and Eastern Daylight Time (EDT, UTC−4) in summer, so people often write ET for both.

The difference between PST and EST

Because the US zones shift together, Pacific time is always exactly three hours behind Eastern time, so you add three hours to go from PST to EST. Winter offset: 3 hours ahead. Summer offset: 3 hours ahead.

When you need it

  • Telling East Coast colleagues when your morning meeting really is.
  • Reading a webinar time given in Pacific time.
  • Planning a flight or a delivery that crosses the country.

Avoiding time zone mistakes

  • Always say the date as well as the time: a late evening in one zone is already tomorrow in another.
  • Prefer city names (New York, Los Angeles) to abbreviations; EST and EDT are different, and many people write EST all year.
  • For international meetings, send the time in UTC or add a link to a converter so everyone sees their own time.

Private by design

The conversion uses your browser's own time zone database, so nothing you enter is sent anywhere.
