Did You Know? — Singapore & New York

Time Zone Facts: Singapore

•Singapore Standard Time (SGT, UTC+8) is the same offset as Beijing, Hong Kong, Kuala Lumpur, and Perth — but Singapore's position just 1.3° north of the equator means the sun rises and sets nearly year-round at 7:00 AM and 7:00 PM.
•Singapore is often called the 'timezone crossroads of APAC': it sits halfway between India (UTC+5:30) and Japan (UTC+9), making it a practical midpoint for pan-Asian meeting schedules.
•As one of the world's few city-states near the equator, Singapore experiences virtually no seasonal variation in daylight — always approximately 12 hours — and never observes DST.

Time Zone Facts: New York

•New York City operates on EST (UTC-5) in winter and EDT (UTC-4) during Daylight Saving Time, which the US observes from the second Sunday in March to the first Sunday in November.
•The New York Stock Exchange on Wall Street opens at 9:30 AM ET and closes at 4:00 PM ET — its trading hours set the pace for global equity markets each business day.
•At 40.7°N latitude, New York sees dramatic daylight swings: just under 9 hours of daylight in late December and over 15 hours in late June.
