What is the time zone of Oregon?
Oregon is divided into two time zones. Almost the full state including cities as Portland, Salem and Eugene is in the Pacific Time zone and observing daylight savings so there are two different time zones depending on the time of year.
- Pacific Standard Time (PST): – 8:00 UTC/GMT (behind)
- Pacific Daylight Time (PDT): – 7:00 UTC/GMT (behind)
Only the majority of Malheur county in the south east corner is in the Mountain Time zone and also observing daylight savings so there are two different time zones depending on the time of year.
- Mountain Standard Time (MST): – 7:00 UTC/GMT (behind)
- Mountain Daylight Time (MDT): – 6:00 UTC/GMT (behind)
All Oregon counties in the state are on Pacific time zone with the exception of Malheur County which has dual time zones. Most of Malheur observes the Mountain time due to its close proximity of Boise, ID. But the south is more connected to Nevada and therefore following the Pacific time.
The official border is defined in the Code of Federal Regulations (CFR) §71.9. (a):
Daylight savings time (DST)
Oregon is using daylight savings as also documented in the Uniform Time Act of 1966. During daylight savings the time changes from Standard time to Daylight time, so PST becomes PDT and MST becomes MDT depending on the location.
It starts on the second Sunday in March and ends on the first Sunday in November. In March the clock is moved forward from 02.00 am to 03.00 am (so you will lose an hour of sleep during the night). While in November it’s reversed as the clock is moved backward from 03.00 am to 02.00 am and you will gain an extra hour of sleep. One way of remembering the movement sequence is that clocks “spring forward and fall back”.
The total period of daylight savings lasts for 34 weeks which is about 65% of the year.
Oregon time news, bills and legislation
There is a continuous debate about which time should be applied. Several bills have been introduced to legalize daylight saving time as the year-round clock, whereas others try to align the time with bordering counties or states. The table below gives an overview of the latest bills in the state of Oregon.
