ICT is 7 hours ahead of GMT at the moment. To convert BST to Thailand Time, add 7 hours to the BST time: 9:00 AM GMT = 4:00 PM ICT.

BST (British Time) is used in United Kingdom from late March to late October. Thailand Time (Thailand time) is used in Thailand.

BST here means British Summer Time, not Bangladesh Standard Time. BST (British Summer Time) is not in force right now: United Kingdom from late March to late October is currently on GMT. This page uses whichever name applies on the date you pick, so the numbers below say GMT.
