What is EST in ICT?
Indochina Time is 11 hours ahead
Eastern Time is on UTC−4:00 and Indochina Time is on UTC+7:00 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
Eastern Time and Indochina 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, 2026Indochina Time is 11 hours ahead
- November 1, 2026 – March 14, 2027Indochina Time is 12 hours ahead
- March 14, 2027 – onwardsIndochina Time is 11 hours ahead
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
Eastern Time
Clocks go back one hour at 2am local time, becoming EST.
Indochina Time
Indochina Time stays on ICT all year, so its offset from UTC never moves.

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