PDT vs EST: Exact Time Difference & Simple Conversion Guide
PDT (Pacific Daylight Time) is UTC−7; EST (Eastern Standard Time) is UTC−5. The exact gap is 3 hours when both are in standard time, or 2 hours during PDT vs EDT daylight overlap.
People confuse them because both abbreviations end with “T” and share similar letters; West-Coast gamers schedule raids in PDT while East-Coast colleagues book EST conference calls, creating missed meetings and frantic Slack pings.
Key Differences
PDT runs March–November in the western U.S.; EST covers the East year-round unless EDT kicks in. Remember: PDT = UTC−7, EST = UTC−5, so 12:00 PDT equals 15:00 EST.
Examples and Daily Life
Setting a 9 a.m. PDT Zoom launch? Tell New York clients it’s noon EST. Checking NFL kickoff? A 5 p.m. EST game starts at 2 p.m. in Los Angeles on PDT.
Does PDT ever equal EST?
No; the shortest gap is 2 hours during daylight-saving overlap, never zero.
How do I convert quickly without math?
Add three hours from PDT to EST from fall to spring; add two hours during daylight-saving months.
