Singapore Is the Fixed End of This Pair
New York is UTC-5 in winter and UTC-4 in summer, and Singapore is UTC+8 all year. That makes the gap 13 hours on EST and 12 hours on EDT. New York moves to EDT on the second Sunday in March and back to EST on the first Sunday in November, and it is the only side that moves.
One way to hold it in your head: the gap is half a day plus an hour in winter and exactly half a day in summer. 9:00 AM in New York is 10:00 PM in Singapore on EST and 9:00 PM on EDT, so a New York morning is Singapore's evening of the same day.
Same Moment, Two Calendars
Because the gap is more than half a day, New York evening times land on the next date in Singapore. Using the winter gap (EST):
| New York | Singapore |
|---|---|
| 6:00 PM | 7:00 AM the next day |
| 8:00 PM | 9:00 AM the next day |
| 10:00 PM | 11:00 AM the next day |
| 11:30 PM | 12:30 PM the next day |
Looking back from Singapore, 9:00 AM there is 8:00 PM the previous day in New York on EST, the evening before. In summer every Singapore time is one hour earlier on New York's clock than it is in winter.
A Slot That Works for Both
The two working days don't overlap, so the workable slot is New York's evening and Singapore's morning. 7:00 to 9:00 PM in New York is 8:00 AM to 10:00 AM the next day in Singapore on EST, and 7:00 AM to 9:00 AM the next day on EDT. New York's early morning gives you Singapore's evening instead, which suits a quick hand-off but not a long discussion.
The summer gap is one hour shorter, not the same, so a call fixed on one clock moves on the other twice a year.
A Monday 8 PM Call That Is Tuesday in Singapore
Consider a call from New York on Monday at 8:00 PM. That's 9:00 AM the next day on EST and 8:00 AM the next day on EDT, both on Tuesday in Singapore. A 9:00 PM start is 10:00 AM the next day on EST.
If Singapore hosts at 9:00 AM Tuesday, New York joins at 8:00 PM the previous day on EST and 9:00 PM the previous day on EDT, Monday evening. A New York calendar and a Singapore calendar therefore show the call on different days, which is the main thing people trip over.
