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

BST is currently 6 hours ahead of CST.

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.

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.

BST is 6 hours ahead of CST for most of the year. Central Standard Time (US) and British Summer Time 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.
