About the time in Rockville
Rockville sits at latitude 39.08, 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.
Rockville runs on America/New_York, which puts the city UTC −4 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Sunrise today lands at 06:27 and sunset at 07:56 local time, giving 13h 29m of daylight. Those figures come from the city's own coordinates (39.08, -77.16) rather than a country-wide average, so they match what you would actually see from a window in Rockville.
