Moon phase today and calendar 2026–2027
The Moon's phase on any date: its name, how much of the disk is lit and how many days have passed since the new moon. In 2027 there are 13 new moons and 12 full moons, US Eastern time; August has two new moons, on the 2nd and the 31st, and the first of them is the day of the total solar eclipse. Below: a calculator that starts at today, and every main phase from October 2026 to December 2027, from the US Naval Observatory.

The eight names
The US Naval Observatory names eight phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Last Quarter and Waning Crescent. The four main ones are moments; here a date gets that name when the moment falls on it in your time zone, and the days in between take the name of the stretch they are in. The Observatory's own daily label follows how much is lit at noon, so on the day before a full moon it can already say Full Moon.
Where Angel Step fits
Angel Step reads only your step count from Apple Health and shows it as one number on a living sky. It does not track the Moon; that is this page's job. A bright Moon makes an evening walk easier to see.
