BST to CST Time — Convert British Summer Time to Central Standard Time (US)

CST is currently 6 hours behind BST.

On Clockjumper, BST refers to British Summer Time (UTC+1), the UK's daylight-saving offset. The same letters are also used locally for Bangladesh Standard Time (UTC+6) — check the city or UTC offset to be sure which is meant.

On Clockjumper, CST refers to US Central Standard Time (UTC−6). The same three letters are also used for China Standard Time (UTC+8) and Cuba Standard Time (UTC−5) — check the city or UTC offset to be sure which is meant.

CST is 6 hours behind BST for most of the year. British Summer Time and Central Standard Time (US) both observe daylight saving, but they change their clocks on different dates, so for a short period each spring and each autumn the gap differs by an hour — the converter above always reflects the correct offset for the date you pick.
