How the gap moves through the year

Singapore is 12 hours ahead of New York for about 8 months of the year.

Singapore is 13 hours ahead of New York for about 4 months of the year.

From the second Sunday in March (when New York moves forward), Singapore is 12 hours ahead of New York.

From the first Sunday in November (when New York falls back), Singapore is 13 hours ahead of New York.

New York moves its clocks forward one hour on the second Sunday in March at 2:00 am local time and back on the first Sunday in November at 2:00 am, switching between Eastern Standard Time (UTC−5) and Eastern Daylight Time (UTC−4).

Singapore does not change its clocks: it stays on UTC+8 (Singapore Standard Time) all year.

Next clock change for this pair, as of when this page was built (2026-10-20): New York falls back on Sun 1 November 2026.

Everything on this page also holds if you swap New York for Toronto, Havana, Montreal, Philadelphia or Port-au-Prince, or Singapore for Shanghai, Beijing, Guangzhou, Shenzhen or Taipei — those cities follow exactly the same clock all year.

Working hours that overlap

In January, two 9-to-5 days never meet — not a single quarter-hour is inside working hours in both cities.

July is no different.

Even with both days stretched to 8:00–18:00 there is no shared hour, so one side always joins outside the office day. Rotating who takes the early or late slot is the usual fix.

Across the week

At 9:00 on a Monday morning in New York, it is 10:00 pm on Monday in Singapore.

6 hours of a New York working week (Monday to Friday, 9 to 5) fall on the weekend in Singapore, so part of Monday or Friday is lost for meetings.

The other way round, 4 hours of a Singapore working week fall on the New York weekend.

Daylight, distance and night calls

New York and Singapore are about 15,340 km (9,530 miles) apart and 178° of longitude apart, which by the sun alone would be 11 hours 45 minutes.

New York's winter clock sits within 4 minutes of the sun, and Singapore's runs 1 hour 5 minutes ahead of the sun.

In mid-January the sun is up in New York from about 7:18 am to 4:52 pm, and the sun is up in Singapore from about 7:12 am to 7:15 pm; there is no moment when both are in daylight.

In mid-July the sun is up in New York from about 5:37 am to 8:27 pm, and the sun is up in Singapore from about 7:05 am to 7:16 pm; both cities are in daylight at the same time for about 3 hours.

In January, 8 hours of a New York office day fall in Singapore's night (10 pm to 6 am), and 6 hours of a Singapore office day fall in New York's night.

In July, 7 hours of a New York office day fall in Singapore's night (10 pm to 6 am), and 7 hours of a Singapore office day fall in New York's night.

Two usual compromises in January: an early call at 7:00 am in New York is 8:00 pm in Singapore; a late call at 6:00 pm in New York is 7:00 am the next day there.

Common mistakes with New York and Singapore

  • Forgetting that the gap changes even though Singapore never touches its clocks: New York does, so a meeting fixed in Singapore time moves by an hour for people in New York.
  • Getting the date wrong. With a gap this large, an afternoon call in one city is the next morning — or the previous evening — in the other. Write the date for both cities in the invite.
  • Writing “EST” all year for New York. In summer the zone is Eastern Daylight Time; calendar apps handle it, but a typed time in an email can be read the wrong way.
