Time Difference Between New York and Singapore
Singapore is 13h ahead of New York in standard time, and 12h ahead while New York is on daylight saving time.
New York clocks move forward on the second Sunday of March and back on the first Sunday of November. Singapore keeps the same clock all year. The figures above cover each part of the year. They do not come from the offset on the day the site was built. The live clocks use the current time.
Working Hours Overlap
For each hour of New York's working day (9:00-18:00), here is the corresponding local time in Singapore. Rows highlighted green fall within standard working hours (9:00-18:00) in both cities. Each block is one part of the year, so the table does not change with the day this page was built.

How the Difference Changes
Only New York changes its clocks, so the gap is not one number. The rules are above. The dates for the year you are reading this page load below.

Working Across New York and Singapore
Twelve hours is the tidiest arithmetic on any of these pages and the least useful. Noon in New York is midnight in Singapore; the AM and PM labels swap and the number stays put. There is no shared working day to find. Two windows exist and both are concessions: 8 AM to 9 AM in New York, which is 8 PM to 9 PM in Singapore, or 8 PM to 10 PM in New York, which is 8 AM to 10 AM the following morning in Singapore. Pick one and keep it, because alternating between them leaves both sides permanently off. Most teams here stop meeting daily and run on written handoffs, with one fixed call a week at an hour nobody enjoys.
Singapore's clock is fixed all year, so New York provides all the movement, and on this pair it does real damage. Singapore is thirteen hours ahead until the second Sunday of March. New York's clocks go forward that day and the gap flattens to twelve hours until the first Sunday of November. When the clocks go back it is thirteen hours again for the rest of the year. Those thirteen-hour stretches break the midnight-noon symmetry that makes the rest of the year easy. 8 PM in New York becomes 9 AM in Singapore instead of 8 AM, and a recurring invite pinned to New York time slides an hour for everyone in Singapore without announcing itself. Check the standing meeting in early March and early November.
The Newark to Singapore nonstop is the longest scheduled passenger flight running, roughly eighteen and a half hours, and the clock arithmetic around it is worth doing before you book. Westbound, flight time and time difference add up to about thirty hours on the calendar: leave Newark late on a Monday night and you land Wednesday morning in Singapore, with Tuesday spent almost entirely in the air. Eastbound the clock gives back more than the flight takes, so a morning departure from Singapore reaches New York the same afternoon. Nobody adjusts to twelve hours quickly. For trips under four days, plenty of regular travelers give up and stay on New York hours the whole time.
