How Many Days Until Fall 2026?

There are 128 days until First Day of Fall 2026, which falls on Tuesday, September 22, 2026. That is 18 weeks and 2 days away, or roughly 4 months. First Day of Fall is an astronomical season that begins at a solstice or equinox, the precise moment Earth's tilt reaches a turning point. First Day of 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 First Day of 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.
