PST to GMT Conversion Guide

Pacific Standard Time (PST) governs the US West Coast (Los Angeles, Seattle, San Francisco) and is 8 hours behind Greenwich Mean Time (GMT) in London. This large gap makes real-time coordination challenging but manageable with the right strategy.

Daylight Saving Transitions (PDT & BST)

During summer daylight saving, both zones shift forward: PST becomes PDT (UTC-7) and GMT becomes BST (UTC+1). The 8-hour difference is maintained for most of the summer, except during the narrow spring/autumn transition windows when the offset is briefly 7 hours.

Business Communication Tips

With an 8-hour gap, the standard workdays barely touch. The ideal window is between 8:00 AM and 9:00 AM PST, which corresponds to 4:00 PM and 5:00 PM GMT. Outside this window, one side will likely be working early morning or late evening.
