About the time in Princeton
Princeton is on daylight saving time at the moment, which is why the offset reads UTC −4 instead of its winter value. Clocks go back on 1 November 2026, and anything scheduled across that date shifts by an hour.
If you are coordinating from another country, the shortcut is the working window: a normal Princeton day of 09:00–17:00 falls between 13:00–21:00 UTC. Convert your own hours into UTC once and you can tell at a glance whether someone there is likely to be at their desk.
The zone identifier America/New_York is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/New_York keeps pointing at New York time whatever the date, which is why every timestamp on this page is built from it.
