What is CET in BST?
British Time is 1 hour behind
Central European Time is on UTC+2:00 and British Time is on UTC+1:00 right now. Both are on daylight saving, so their clocks read CEST and BST. That gap holds all year, because both zones change their clocks together.

Scheduling between the two
Working hours overlap from 10:00 am to 6:00 pm CEST, which is 9:00 am to 5:00 pm BST. Anything inside that window falls in the normal working day at both ends.
A note on BST: it can also mean Bangladesh Standard Time (UTC+6). This page means British Summer Time.
Central European Time (CEST) is used in Berlin, Madrid, Rome, Amsterdam, Warsaw and Stockholm
British Time (BST) is used in the whole United Kingdom. In winter the UK is on GMT; from late March to late October it is on BST, an hour ahead.
