Every Singapore hour with the New York time in both seasons. Singapore mornings are the previous evening in New York (−1).

A near-perfect half-day gap

With a 12-hour gap in the US summer, the clock faces in Singapore and New York show the same numbers, just with AM and PM swapped: 9:00 AM in Singapore is 9:00 PM the evening before in New York. In winter, when the East Coast is on EST, add one more hour of difference.

This makes the US evening and the Singapore morning the natural meeting time. A New York call at 8:00 PM EDT is 8:00 AM the next day in Singapore, and the same call at 8:00 PM EST is 9:00 AM. Teams that meet weekly usually fix the slot in one city and let the other side move by an hour twice a year.

When the gap changes

Singapore has used UTC+8 without daylight saving since 1982. The US East Coast moves to EDT at 2:00 AM on the second Sunday of March and back to EST at 2:00 AM on the first Sunday of November, as overseen by the US Department of Transportation.

Scheduling tips

Singapore–New York checklist

  • Use the US evening / Singapore morning window for regular calls.
  • Write the date for both cities; they differ for most of the day.
  • Move recurring calls in March and November if they are fixed in one city's time.
  • Friday evening in New York is already Saturday morning in Singapore.
  • For India, the gap is fixed: see IST to SGT.

The live Kuala Lumpur, Washington, DC and Toronto clocks show both sides. For the US West Coast, use SGT to PST, and for the Philippines, PHT to EST.
