Does daylight saving time change the BST–PST difference?

The labels BST and PST are fixed offsets, so the result on this page is always exact. Both regions move their clocks for daylight saving on roughly the same weekends, so the 9 hours gap usually holds steady right through the year.

How accurate is this BST to PST conversion?

We don’t guess. BST and PST times are worked out from the official IANA time zone database, the trusted standard that operating systems use worldwide. Because daylight-saving rules and regional offsets do change over time, we track those updates rather than relying on a fixed number — which is exactly where many converters slip up.
