UTC to PST Converter

UTC to PST Conversion Table

Full 24-hour table. PST is UTC-8 and PDT is UTC-7 (second Sunday in March to first Sunday in November).

* Before 08:00 UTC on PST (07:00 on PDT) the Pacific time falls on the previous calendar day.

When the Clocks Change

Pacific Time moves forward at 2:00 AM on the second Sunday in March and back at 2:00 AM on the first Sunday in November.

Converting a Timestamp in Code

# Python 3.9+
from datetime import datetime
from zoneinfo import ZoneInfo
datetime.fromisoformat("2026-03-01T15:00:00+00:00").astimezone(ZoneInfo("America/Los_Angeles"))

// JavaScript
new Date("2026-03-01T15:00:00Z").toLocaleString("en-US", { timeZone: "America/Los_Angeles" })

Both give the PST time shown above.
