In September 2026: last quarter on September 4, new moon on September 11, first quarter on September 18, and full moon on September 26. The dates and times follow Universal Time until your browser converts them to your own time zone, so a phase that falls near midnight can land on the day before or after where you live.
The full moon of September is traditionally called the Corn Moon. That night the Moon is 379,423 km from Earth.
For stars, meteors and the Milky Way, the darkest nights run from September 8 to September 14, around the new moon, when the Moon stays out of the evening sky.
