Time Zone Math: 9:00 AM Tennessee = 8:00 AM Washington State

Tennessee (Central Time) is 1 hour ahead of Washington (Pacific Time).

Conversion

9:00 AM CT (Tennessee) = 8:00 AM PT (Washington).
Applies year-round except during the ~1-week mismatches in March/November when one region switches DST before the other (US switched uniformly since 2007, so mismatches are rare).

Period	Tennessee	Washington	Diff
Standard Time (Nov–Mar)	CST (UTC−6)	PST (UTC−8)	2 hrs
Daylight Time (Mar–Nov)	CDT (UTC−5)	PDT (UTC−7)	2 hrs

Wait—standard offset is 2 hours, not 1. My earlier statement was incorrect.

Correction: 9:00 AM in Tennessee = 7:00 AM in Washington (2-hour difference).

Some think Central→Pacific is 1 hour (it's Mountain→Pacific). Central is 2 hours ahead of Pacific.

Always verify with a time-zone converter (timeanddate.com, worldtimebuddy.com) for specific dates.
