Eastern Time to Pacific Time Calculator

Eastern Time to Pacific Time Calculator

Need to schedule a call with someone on the West Coast? Or maybe you're watching a live event and want to know when it airs in your zone?

This ET to PT Calculator instantly converts any Eastern Time (ET) to Pacific Time (PT). It handles both standard and daylight saving time automatically.

No guesswork. No mental math. Just accurate results in seconds.

Understanding the Time Difference

The US has multiple time zones. Eastern and Pacific are the two most commonly compared.

Here's the key difference:

• EST (Eastern Standard Time) is UTC-5. Active in winter months.
• EDT (Eastern Daylight Time) is UTC-4. Active during DST (spring/summer/fall).
• PST (Pacific Standard Time) is UTC-8. Active in winter months.
• PDT (Pacific Daylight Time) is UTC-7. Active during DST.

The gap between ET and PT is always 3 hours. Pacific Time is always 3 hours behind Eastern Time — whether it's standard or daylight saving.

Standard Time vs Daylight Saving Time

Both zones shift their clocks simultaneously. So the 3-hour difference stays constant year-round.

However, the label changes:

• Winter: EST → PST (both on standard time)
• Summer: EDT → PDT (both on daylight saving time)

Our calculator automatically detects which is in use for your selected date.

Conversion Example

Example 1: Morning Meeting

You have a 9:00 AM EST meeting. What time is that for your colleague in Los Angeles?

• 9:00 AM EST − 3 hours = 6:00 AM PST

That's an early morning call for them. You might want to reschedule!

Example 2: Evening Event (DST Active)

A live webinar starts at 7:30 PM EDT on June 15. When does it air in Seattle?

• 7:30 PM EDT − 3 hours = 4:30 PM PDT

Comfortable afternoon viewing for Pacific Time viewers.

Example 3: Midnight Crossover

A sports event starts at 1:00 AM EST on February 10. What time is it in San Francisco?

• 1:00 AM EST − 3 hours = 10:00 PM PST on February 9

Notice the date rolled back! This is why the date field matters in conversions.
