Understanding PST to EST Conversion
What is the time difference between PST and EST?
Pacific Standard Time (PST) is 3 hours behind Eastern Standard Time (EST). This means when it's 1:00 PM (13:00) in PST, it's 4:00 PM (16:00) in EST.
PST (Pacific Standard Time)
UTC-8:00 during standard time
UTC-7:00 during daylight saving (PDT)

EST (Eastern Standard Time)
UTC-5:00 during standard time
UTC-4:00 during daylight saving (EDT)

Daylight Saving Time Considerations
Both PST and EST observe Daylight Saving Time, but the time difference remains constant at 3 hours. During DST, PST becomes PDT (Pacific Daylight Time) and EST becomes EDT (Eastern Daylight Time).
