What Is Pacific Daylight Time?
It covers all or parts of five states in the US and two provinces or territories in Canada.
The PDT time zone is the third most populated time zone in the US. It spans from Canada to Mexico.
In North America, Pacific Daylight Time shares a border with Mountain Standard Time (MST) in the east.
PDT or PST?
Pacific Daylight Time (PDT) is a North American time zone in use from the second Sunday in March to the first Sunday in November during Daylight Saving Time (DST). Pacific Standard Time (PST) is used during the remainder of the year.
PDT is the Pacific Time Zone
In everyday usage, PDT is often referred to as Pacific Time (PT) or the Pacific Time Zone. This can add a bit of confusion as the term Pacific Time does not differentiate between standard time and Daylight Saving Time, so Pacific Time switches between PDT and PST in areas that use DST during part of the year.
