Time in PDT now refers to the current time in the Pacific Daylight Time (PDT) time zone. PDT is a daylight saving time that is observed in western North America, including the states of California, Oregon, and Washington in the United States, and the province of British Columbia in Canada.
PDT is typically observed from the second Sunday in March to the first Sunday in November. During this time, clocks are set one hour ahead of Pacific Standard Time (PST). The purpose of daylight saving time is to make better use of daylight hours during the summer months, when the sun rises earlier and sets later.
