SGT to EST Converter (Singapore Time to Eastern Time)

Mid-January 2026: EST is 13 hours behind SGT. Mid-July 2026: EDT is 12 hours behind SGT.

Singapore is on UTC+08:00 all year. It has no daylight saving time and sits so close to the equator that day length hardly varies. New York is on UTC−05:00 in winter and UTC−04:00 in summer, so the Eastern time is 13 hours behind in winter and 12 hours behind from March to November. For most of Singapore's day, the date in New York is the day before.

Singapore adopted UTC+08:00 on January 1, 1982, moving from UTC+07:30 so that its clocks matched those of Malaysia and other neighbors. Business with the United States, from banking to technology and shipping, relies on this opposite-day-and-night relationship.

How to use this tool

1. Pick a date and time in SGT. The date matters when daylight saving time is in force.
2. Read the matching time in EST, with both UTC offsets.
3. Use "Use current time" for now, or the tables below for a quick look.

Formula

EST time = SGT time − (SGT UTC offset) + (EST UTC offset)

The converter looks up both UTC offsets for the actual instant in the saved IANA time zone rules, so daylight saving changes are included automatically.

Example

Worked with the saved rules:

9:00 AM SGT on March 2, 2026 = 8:00 PM EST (previous day)

6:30 PM SGT on August 3, 2026 = 6:30 AM EDT

Time difference through the year

The difference depends on the date when either place moves its clocks. These are the offsets on two reference days, from the saved IANA rules:

Clock changes in 2026

Between these dates the difference shifts by the size of the change.

A hub in Asia dealing with the East Coast

Singapore hosts regional offices for many American companies. A team lead at 9:00 a.m. in Singapore is dealing with an Eastern evening of 8:00 p.m. on the previous date in winter, or 9:00 p.m. in summer, so cross-ocean calls are held either at the end of the Singapore day or the start of the New York one.

Airlines run some of the longest nonstop services in the world between Singapore and the New York area, with a flight time of around 18 hours. A night departure from Singapore lands in the New York area early the next morning by the local clock.

Handling the date in messages

Always give the date as well as the hour when you propose a time. "Wednesday 8 a.m. Singapore" is Tuesday 7 p.m. in New York in winter, and the difference between Tuesday and Wednesday is where scheduling errors start.

If your plan includes the weeks of the US clock change, remember that Singapore stays put. The same Singapore time falls an hour earlier on the New York clock from the second Sunday of March until the first Sunday of November.
