About the time in Cambridge
Sunrise today lands at 06:45 and sunset at 08:12 local time, giving 13h 27m of daylight. Those figures come from the city's own coordinates (40.02, -81.59) rather than a country-wide average, so they match what you would actually see from a window in Cambridge.
If you are coordinating from another country, the shortcut is the working window: a normal Cambridge 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.
Cambridge sits at latitude 40.02, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 27m is one point on that curve, not a fixed value.
