About the time in Casper
Around 60,285 people live in Casper, and all of them keep the same civil time, so the reading above applies to the whole urban area — not just the city centre.
Sunrise today lands at 06:18 and sunset at 07:59 local time, giving 13h 41m of daylight. Those figures come from the city's own coordinates (42.87, -106.31) rather than a country-wide average, so they match what you would actually see from a window in Casper.
Casper runs on America/Denver, which puts the city UTC −6 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.
