About the countdown to Autumn
Grouping autumn as September through November keeps the three coolest transition months together, which is what makes seasonal climate statistics comparable year on year.
In the Southern Hemisphere September 1 opens meteorological spring.
The counter above reads from your device clock and refreshes every second, so the days, hours, minutes and seconds always reflect the time remaining right now. The next Autumn falls in ISO week 35 of 2027. When the day arrives the page says so instead of showing a zero, and from the following day it moves its target to 2028, so the countdown never runs out of road.
Around the same time
These fall within a fortnight of Autumn, which is useful if you are planning around the date rather than only checking it.

| World Photography Day | 19 August 2027 | 13 days before |
