PST to BST Conversion Guide

What is PST to BST Conversion?

PST to BST conversion helps you translate time between Pacific Standard Time and British Summer Time zones. PST is UTC-8 during standard time and UTC-7 during daylight saving time (PDT). BST is UTC+1 during summer months and reverts to GMT (UTC+0) during winter. The time difference varies between 8-9 hours depending on which zones are observing daylight saving time, with BST being ahead.

Time Zone Information

Pacific Standard Time (PST): Used on the US West Coast including California, Oregon, Washington, and parts of Canada. UTC-8 during standard time, UTC-7 during daylight saving time (PDT) from second Sunday in March to first Sunday in November.

British Summer Time (BST): Used in the United Kingdom during summer months from the last Sunday in March to the last Sunday in October. UTC+1 during BST, reverts to GMT (UTC+0) during winter.

Time Difference: BST is 8 hours ahead of PST during overlapping daylight saving periods and 9 hours ahead when only one zone observes daylight saving time.

Daylight Saving Time Impact

PST observes DST: From second Sunday in March to first Sunday in November, PST becomes PDT (UTC-7)

BST is summer time: From last Sunday in March to last Sunday in October, UK observes BST (UTC+1), otherwise GMT (UTC+0)

Complex overlap: The time difference can be 8 or 9 hours depending on which zones are in daylight saving time

Conversion Tips & Best Practices

• BST is 8 hours ahead of PST/PDT - good for same-day business meetings

• Both zones observe daylight saving time but with slightly different start/end dates

• Best meeting times: PST morning (8-11 AM) converts to BST afternoon (4-7 PM)

• BST only exists during summer; UK uses GMT (UTC+0) during winter months

• UK business hours are typically 9 AM to 5 PM BST/GMT

• Consider that time difference can briefly change when zones transition on different dates
