Sunrise today lands at 06:45 and sunset at 08:26 local time, giving 13h 41m of daylight. Those figures come from the city's own coordinates (42.69, -83.12) rather than a country-wide average, so they match what you would actually see from a window in Rochester.
Around 12,711 people live in Rochester, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
Rochester 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.
