Difference Between PST and EST - Pacific vs. Eastern Standard Time Comparison Summary

What is PST

PST is also known as Pacific Standard Time or Pacific Time. This time zone is 8 hours behind the Coordinated Universal Time – UTC. This is also indicated as UTC -8.  Time in this zone is calculated using the mean solar time of the 120th meridian west of the Greenwich Observatory. PST is used during the standard time in some parts of North America. It is typically used during winter because PDT (Pacific Daylight Time) is used during the summer since some areas use daylight saving time. During PDT, the time offset of this zone is UTC-7.

PST = UTC – 8

PDT = UTC – 7
