About the time in Boulder
Boulder sits at latitude 40.01, in the mid-latitude band, so day length here swings noticeably between midwinter and midsummer — today's 13h 32m is one point on that curve, not a fixed value.
Boulder 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.
Boulder is on daylight saving time at the moment, which is why the offset reads UTC −6 instead of its winter value. Clocks go back on 1 November 2026, and anything scheduled across that date shifts by an hour.
