Pacific Daylight Time Zone - PDT

Pacific Daylight Time is seven hours behind the Coordinated Universal Time standard, written as an offset of UTC - 7:00. That means to find the standard time in the zone you must subtract seven hours from Coordinated Universal Time.

Territories observing the time zone are primarily in North America. It runs through several U.S. states, including California, Idaho, Nevada, Oregon, and Washington. It also passes through Canada in the North, and Mexico in the South.

Depending on where the time zone is being referenced, it may be called one of these additional names:

• Pacific Daylight Saving Time or PDST

• North American Pacific Daylight Time or NAPDT

• Heure Avancée du Pacifique or HAP (in French)

In many of the areas where this time zone is used, during the fall to winter months Pacific Standard Time, or PST, is observed, and then during Daylight Saving (spring to summer months) Pacific Daylight Time or PDT is used.
