About time in Aurora
Aurora stretches across three counties — Arapahoe, Adams, and a corner of Douglas — on the plains east of Denver, and is Colorado's third-most-populous city; its clocks never differ from its bigger neighbor's.
Founded in 1891 as the town of Fletcher and renamed in 1907, Aurora today hosts Buckley Space Force Base, where missile-warning satellite operations run continuously on UTC no matter what the local Mountain Time reading says.
Sharing Denver's latitude, Aurora gets close to 15 hours of daylight at midsummer and a little over 9 hours at the December solstice; the March clock change pushes sunset from just after 6:00 PM to just after 7:00 PM overnight.
