There are 116 days until Fall 2026, which falls on Tuesday, September 22, 2026. That is 16 weeks and 4 days away, or roughly 3 months. Fall is an astronomical season that begins at a solstice or equinox, the precise moment Earth's tilt reaches a turning point. Fall falls on a Tuesday this year, a midweek date — worth noting if you want to plan time off around it.
Counting down turns a vague "soon" into a clear number of days you can plan around — booking travel, sending cards, or simply building anticipation. Many people begin preparing for a date like this two to three months ahead, and a visible countdown helps pace that preparation rather than leaving everything to the final week. If you are counting down to Fall, you can add a free Outside countdown widget to your iPhone home screen; it updates every day and can be shared with friends and family.

The Science Behind Fall
Seasons are driven by the tilt of Earth's axis — roughly 23.5 degrees — not by how close the planet is to the Sun. As Earth orbits, each hemisphere leans toward or away from the Sun, changing the angle of sunlight and the length of the day. The astronomical start of a season is pinned to a solstice or an equinox, the precise moment that geometry reaches a turning point.
That is why the start of Fall 2026 lands on a specific date and even a specific time, rather than the first of a month. Equinoxes bring near-equal day and night worldwide; solstices mark the longest or shortest day of the year. Knowing the exact changeover is useful for gardeners, photographers, and anyone tracking daylight hours.
