PDT vs. EDT: Know the Difference
By Shumaila Saeed || Published on January 1, 2024
PDT (Pacific Daylight Time) and EDT (Eastern Daylight Time) are time zones in the United States; PDT is 3 hours behind EDT.
Key Differences
PDT (Pacific Daylight Time) is a time zone used in the western part of the United States, typically observed during the summer months. EDT (Eastern Daylight Time), on the other hand, is the time zone used on the east coast during the same period. These designations are part of Daylight Saving Time adjustments.

During Daylight Saving Time, clocks in the PDT zone are set one hour ahead of Pacific Standard Time (PST), while those in the EDT zone are set an hour ahead of Eastern Standard Time (EST). This results in a three-hour time difference between PDT and EDT.

The transition to PDT typically occurs in the spring and lasts until the fall, aligning with the practice of setting clocks forward to extend evening daylight. Similarly, the transition to EDT follows the same principle, albeit for the eastern region.
