This monthly moon phase calendar for August 2026 shows a phase icon and illumination percentage for every day. Major phases—new moon, first quarter, full moon, and last quarter—are highlighted so you can spot them while scanning the grid.

How to read the grid

Each cell uses a parametric moon disc that matches illumination and waxing/waning direction. Hover (or long-press) a day for the phase name and lit percentage. Use the location control if you also want rise and set context on related today pages for the same city.

Illumination is the fraction of the near side that appears lit from Earth. It grows through waxing phases toward full moon, then shrinks through waning phases back to new moon on the roughly 29.53-day synodic cycle.

Planning with August moons

Photographers often prefer full moons near sunset and darker skies near new moon. Pair this calendar with today’s moon phase, sunrise and sunset, and 2026 full moons.

Frequently asked questions

What does the moon phase calendar show?

Each day in August 2026 includes a moon disc icon, a short phase label, and an illumination percentage. Major phases such as new and full moon are highlighted on the grid.

Why does illumination change every day?

As the Moon orbits Earth, the sunlit portion of the near side changes. Illumination rises from new moon toward full moon, then falls through the waning phases. Values are computed for local noon so the calendar stays stable across time zones.

Can I change city on the calendar page?

Yes—use the location selector to keep your preferred city cookie. Rise and set details appear on the today view for that city; the month grid focuses on phase and illumination for each date.

Where do I find full moon dates for the year?

Open the full moon year list for 2026, or use the next major phases cards on the moon phases hub for the nearest full moon with a countdown.
