About New York time
New York City runs on Eastern Time and sets the tempo for U.S. financial markets — the New York Stock Exchange opens at 09:30 local time, a moment watched around the world.
Because Wall Street trades on Eastern Time, a huge slice of global scheduling quietly anchors to New York. When New York switches DST two weeks before Europe, there is a short window each spring and autumn where the usual London–New York gap shrinks or grows by an hour — a classic source of missed calls. The ball drop in Times Square at midnight on December 31 is effectively the world’s most-watched local timestamp.
