About the time in Ontario
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.
Ontario sits at latitude 40.76, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 29m is one point on that curve, not a fixed value.
Ontario 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.
