Eastern Time (ET)
New York operates on Eastern Time (ET). New York observes Daylight Saving Time, springing forward one hour in March and falling back in November. During DST, the abbreviation changes to reflect the shift.
Time Zone: Eastern Time (ET) — Standard Offset: UTC-5 (EST) — DST Offset: UTC-4 (EDT)
Country: United States
This city observes Daylight Saving Time, so the UTC offset changes twice per year. Always verify the current offset when scheduling across time zones.
New York City is home to Wall Street, the New York Stock Exchange (NYSE), and NASDAQ — the two largest stock exchanges in the world by market capitalization. The NYSE trading floor opens at 9:30 AM ET and closes at 4:00 PM ET, making Eastern Time one of the most closely watched time zones in global finance. Pre-market trading begins as early as 4:00 AM ET, and after-hours trading extends to 8:00 PM ET. If you work in finance, tech, media, or advertising, chances are you need to coordinate with someone in New York regularly.
New York observes Daylight Saving Time from the second Sunday in March through the first Sunday in November. During DST, clocks spring forward one hour — meaning New York shifts from EST (UTC-5) to EDT (UTC-4). This change affects scheduling with cities that don't observe DST. For example, the time difference between New York and London is normally 5 hours, but shrinks to 4 hours for a few weeks in March when the US changes clocks before the UK does, and again briefly in the fall.
If you're calling New York from the West Coast, remember you're 3 hours behind — a 9 AM call in New York is 6 AM in Los Angeles. From London, New York is 5 hours behind during winter (4 during summer), so a 2 PM London call catches New York at 9 AM. From Tokyo, New York is 14 hours behind (13 during DST), making early morning Tokyo calls align with New York's late afternoon.
New York shares Eastern Time with major cities including Washington D.C., Atlanta, Miami, Boston, Philadelphia, and Toronto. The Eastern time zone covers roughly 23% of the US population, making it the most populous US time zone. New York's media industry drives the news cycle — the major morning shows (Today, Good Morning America) air live at 7 AM ET, and prime-time television runs from 8 PM to 11 PM ET across the Eastern and Central zones.
