When the difference changes

Pacific Time and British Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:

Now – March 14, 2027British Time is 8 hours ahead
March 14, 2027 – March 27, 2027British Time is 7 hours ahead
March 27, 2027 – October 30, 2027British Time is 8 hours ahead
October 30, 2027 – November 7, 2027British Time is 7 hours ahead
November 7, 2027 – onwardsBritish Time is 8 hours ahead

Periods shorter than a day are not listed. Each zone changes at its own local time, so on a date when both move there are a few hours when the gap is briefly something else.

A note on BST: it can also mean Bangladesh Standard Time (UTC+6). This page means British Summer Time.
