The acronym PDT expands to which phrase?

• A. Pacific Daylight Time Zone
• B. Pacific Daylight Time
• C. Pacific Daylight Timing
• D. Pacific Daylight Standard Time

Answer: (B)

Understanding how time zone names work helps here. PDT stands for Pacific Daylight Time, the daylight-saving form of the Pacific Time Zone. It indicates the time used when daylight saving is in effect, typically UTC-7. The other phrases aren’t standard labels for this time: adding “Zone” is unnecessary when naming the current time, “Timing” isn’t the established designation, and “Standard Time” would refer to Pacific Standard Time (PST), which is used outside daylight saving periods. So the correct form is Pacific Daylight Time.
