On Friday, October 9, 2026, the moon phase today in the United States is a New Moon, with 0% illumination. Next full moon: Oct 26.
The Moon wobbles slightly as it orbits Earth — a phenomenon called libration. Hit Animate Day to watch the surface shift live. Over time, this lets us see 59% of the lunar surface rather than just 50%.

A Field Guide to the Moon's Phases
The Moon's shape never actually changes — what shifts is how much of its sunlit half faces Earth at any given moment. That one variable, playing out across a roughly 29.5-day orbit, is responsible for all eight phases and everything worth noticing about each one.
Viewing conditions across the US
The lower 48 sit between roughly 25°N and 49°N, a band narrow enough that most Americans see fairly similar Moon behavior — a high, steep arc in winter and a lower, lazier path in summer. Step outside that range, though, and things shift: Hawaii's latitude near 20°N puts the Moon on a much more vertical track, closer to how it looks near the equator, while Alaska stretches up past 70°N, where the seasonal swing becomes severe enough that a winter full moon can stay up for days and a summer one barely clears the horizon. Use the calculator above for exact moonrise, moonset, and phase times for your specific location.
