BST to CDT Time — Convert British Summer Time to Central Daylight Time (US)

CDT 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.

CDT is 6 hours behind BST for most of the year. British Summer Time and Central Daylight 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.
