Pacific Time to Eastern Time (PT to ET)
To convert Pacific Time to Eastern Time (PT to ET): in summer 9:00 AM PDT is 12:00 PM EDT, and in winter 9:00 AM PST is 12:00 PM EST. The gap holds all year, because both ends switch together.
In Eastern Daylight Time
- On a 24-hour clock
- 09:00 PDT is 12:00 EDT
- The offsets
- PDT is UTC-07:00, EDT is UTC-04:00
- Difference
- EDT is 3 hours ahead of PDT
- Date
- Same calendar day.
- This gap holds all year
- Both zones switch on the same dates, so they move together.
- PDT is only in force part of the year United States: daylight time starts the second Sunday in March, at 02:00 local time and ends the first Sunday in November, at 02:00 local time (Energy Policy Act of 2005, in force since 2007). In 2026 that is 2026-03-08 to 2026-11-01. Los Angeles is on PST between those dates.
- otherwise PST, UTC-08:00
- Military time zone letters Z (Zulu) is UTC. A to M run east of Greenwich an hour apart, N to Y west, and J is left out. A letter names an offset, so a zone that switches to daylight time changes letter: EST is R, EDT is Q.
- PDT is T (Tango), EDT is Q (Quebec)

How the Time Zone Converter works
PT means Pacific Time, whichever of its two offsets is in force: PST at UTC-08:00 in winter, and PDT at UTC-07:00 from the second Sunday in March to the first Sunday in November. ET means Eastern Time, whichever of its two offsets is in force: EST at UTC-05:00 in winter, and EDT at UTC-04:00 from the second Sunday in March to the first Sunday in November. So converting PT to ET is the same arithmetic all year: ET is 3 hours ahead of PT.
The gap between these two does not change during the year. Both ends switch to daylight saving on the same dates under the United States rule, so they move together: PST to EST in winter and PDT to EDT in summer are both 3 hours. Only the abbreviations change.
Worked through: in summer, 9:00 AM PDT is 12:00 PM EDT. In winter, 9:00 AM PST is 12:00 PM EST.
Three hours forward, all year, and the reason west coast finance starts before dawn. The New York Stock Exchange opens at 9:30 AM Eastern, which is 6:30 AM Pacific in every season, and closes at 4:00 PM Eastern, 1:00 PM Pacific. The same arithmetic runs the other way at the end of the day: 2:00 PM in California is 5:00 PM in New York, so a request sent after lunch on the west coast arrives as the east coast is leaving.
PST to EST has its own page, and it is a different question. That page converts the abbreviations exactly as written, which is right when an invitation names a specific offset. This one converts the zone (the clock on the wall in Los Angeles), which is almost always what someone typing PT to ET wants. The converter above is preset to the summer pairing, PDT to EDT, because that is in force for about eight months of the year; for a date between November and March, pick PST and EST in the lists instead.
Common times for this pair, summer and winter:
- 6:30 AM PDT is 9:30 AM EDT; in winter, 6:30 AM PST is 9:30 AM EST - 9:00 AM PDT is 12:00 PM EDT; in winter, 9:00 AM PST is 12:00 PM EST - 1:00 PM PDT is 4:00 PM EDT; in winter, 1:00 PM PST is 4:00 PM EST - 5:00 PM PDT is 8:00 PM EDT; in winter, 5:00 PM PST is 8:00 PM EST
Time Zone Converter FAQ
What is the time difference between PT and ET?
3 hours, all year: ET is 3 hours ahead of PT. In winter that is PST to EST and in summer PDT to EDT, and both pairings have the same gap because the two ends switch together.
What time is 9:00 AM PT in ET?
In summer, 9:00 AM PDT is 12:00 PM EDT. In winter, 9:00 AM PST is 12:00 PM EST.
Is PT the same as PST?
Only in winter. PT is Pacific Time, whichever offset is in force: PST at UTC-08:00 from the first Sunday in November until the second Sunday in March, and PDT at UTC-07:00 the rest of the time. PST written in July is, strictly, an hour away from the clock in Los Angeles. That is why PT is the safer thing to write in an invitation that has to be right all year.
When does the difference between PT and ET change?
It does not. Both ends switch under the United States rule on the same dates (in 2026, 2026-03-08 and 2026-11-01), so the abbreviations change and the gap of 3 hours stays put.
Is there anything specific to this pair worth knowing?
Three hours forward, all year, and the reason west coast finance starts before dawn. The New York Stock Exchange opens at 9:30 AM Eastern, which is 6:30 AM Pacific in every season, and closes at 4:00 PM Eastern, 1:00 PM Pacific. The same arithmetic runs the other way at the end of the day: 2:00 PM in California is 5:00 PM in New York, so a request sent after lunch on the west coast arrives as the east coast is leaving.
