What is ICT in EST?
Eastern Time is 11 hours behind
Indochina Time is on UTC+7:00 and Eastern Time is on UTC−4:00 right now. Eastern Time is on daylight saving, so its clocks read EDT. The gap changes during the year — see below.

When the difference changes
Indochina Time and Eastern Time do not change their clocks on the same dates, so the gap between them is not the same all year. Most converters show only today’s figure. These are the periods ahead:
- Now – November 1, 2026Eastern Time is 11 hours behind
- November 1, 2026 – March 14, 2027Eastern Time is 12 hours behind
- March 14, 2027 – onwardsEastern Time is 11 hours behind
Periods shorter than a day are not listed: both zones change at 2am in their own local time, so there are a few hours on each transition date when the gap is briefly something else.
Daylight saving
Indochina Time
Indochina Time stays on ICT all year, so its offset from UTC never moves.
Eastern Time
Clocks go back one hour at 2am local time, becoming EST.

Scheduling between the two
There is no overlap between a nine-to-six working day in Bangkok and one in New York — the gap is too wide. A call has to sit early or late for one side. Early morning in Bangkok is the usual compromise, since that is late afternoon or evening in New York.
Indochina Time (ICT) is used in Thailand, Vietnam, Cambodia and Laos
Eastern Time (EDT) is used in Toronto, Atlanta, Miami, Detroit and most of the US east coast
