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

BST is currently 6 hours ahead of CDT.

Daylight saving and how the gap changes

BST is 6 hours ahead of CDT for most of the year. Central Daylight 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.
