About This Overlap
Thailand is South-East Asia's tourism and cultural hub with growing India ties in manufacturing and trade. IST is 1h 30m ahead of ICT year-round (no DST). India's 9 AM = 7:30 AM Bangkok; India's 5 PM = 3:30 PM Bangkok — excellent overlap. Thailand's manufacturing sector and Indian restaurants/cultural presence make it a bridge between India and ASEAN.
