Las Vegas, set in the Mojave Desert at roughly 36°N latitude and 115°W longitude, experiences dramatic swings in daylight throughout the year. Its location near the western edge of the Pacific Time Zone means that clock time (PST/PDT) is based on the 120th meridian, about 20 minutes ahead of local apparent solar time. This offset, combined with Daylight Saving Time (which shifts clocks forward one hour from March to November), pushes sunrises and sunsets later relative to the clock. For example, the latest sunrise in December (around 6:50 AM) occurs over an hour after astronomical dawn, while the latest sunset in June (around 8:05 PM) gives way to a long, golden evening. The tables below detail the key seasonal milestones, including the longest and shortest days, plus ideal windows for photography (the golden hours).
