PST / EST or Pacific / Eastern local time?
PST and EST are fixed standard-time labels. A real Los Angeles or New York meeting can use daylight time instead. Use date-aware mode for the local event; use fixed mode when the supplied offsets explicitly mean PST and EST.
The date-aware converter rejects a source time skipped by a clock change. When a local time occurs twice, select its earlier or later occurrence so the target identifies one exact instant.

- Choose Pacific to Eastern or Eastern to Pacific.
- Enter the calendar date and clock time in the source zone.
- Select date-aware local zones for a real meeting, or fixed PST/EST for literal standard-time labels.
- Read the destination time, full date, UTC offsets and any next-day or previous-day label.
Convert Eastern to Pacific time with a source date, previous-day results and date-aware daylight-saving rules.
How the result is calculated
The calculator validates the required dates, units and range before producing a result. Keep the inputs and the selected convention with the output so another person can reproduce it.

Keep the inputs and conventions beside the answer. These values explain what the result measures.
| Result field | Meaning |
|---|---|
| Destination time and date | The same instant displayed in the destination, with next-day or previous-day rollover preserved. |
| Source and destination offsets | The explicit UTC relationship used for the selected instant and convention. |
| Time convention | Date-aware Los Angeles/New York rules or literal fixed PST/EST offsets. |
| Repeated-time choice | The earlier or later occurrence when a source local hour happens twice. |
Midnight changes the destination date
January 10, 2027 at 11 PM PST is January 11 at 2 AM EST. Converting January 11 at 1 AM EST back gives January 10 at 10 PM PST.
Try the example in the calculator above. Change one input at a time and compare the target, interval and selected rules. For a longer explanation read PST to EST: Dates, Daylight Saving and Meeting Times.
Conventions to keep with your result
Literal PST is UTC−08:00 and EST is UTC−05:00. Date-aware mode uses Los Angeles and New York, including the runtime’s daylight-saving rules. A skipped source time is rejected; a repeated source time needs an earlier/later choice.
EST to PST Converter: frequently asked questions
Is Eastern always three hours ahead?
The fixed PST/EST labels differ by three hours. Los Angeles and New York normally do too, but the gap can temporarily differ while their clock changes occur at different UTC instants.
What happens at midnight?
The destination’s date moves to the next or previous calendar date when necessary.
Does this work in later years?
The selected date uses the browser’s available IANA rules rather than a frozen annual offset list. Future rule changes require updated runtime time-zone data.
Are the live clocks always labeled PST and EST?
No. The live local clocks display their current abbreviation and offset, including PDT/EDT when applicable.
