PST to EST Converter
Offset
EST ahead
Quick Answer
EST is 3 hours ahead of PST — always.
Add 3 hours to convert PST → EST. This never changes, even during daylight saving time.
PST to EST — The 3-Hour Rule
The Pacific to Eastern time conversion is the most common US time zone conversion. Since both zones observe daylight saving time simultaneously, the 3-hour difference is constant year-round. Simply add 3 hours to any Pacific time to get Eastern time.
Common Conversions
- 9 AM PST = 12 PM (noon) EST
- 12 PM PST = 3 PM EST
- 3 PM PST = 6 PM EST
- 6 PM PST = 9 PM EST
- 9 PM PST = 12 AM (midnight) EST (+1 day)
Cross-Coast Scheduling Tips
For teams spanning both coasts, the ideal meeting window is 9 AM - 2 PM Pacific (12 PM - 5 PM Eastern). Early morning Pacific calls (before 9 AM) work well for East Coast mornings.
Why PST and EST Always Differ by 3 Hours
Unlike the London-to-EST conversion which fluctuates during DST transitions, PST and EST always maintain a 3-hour gap. Both zones follow the US DST schedule (second Sunday of March, first Sunday of November), so they shift together. This makes PST↔EST the simplest US timezone conversion.
