How many days until autumn?

Meteorological autumn in Australia begins on 1 March and runs through to the end of May, following the same fixed calendar-month system used for all four seasons locally rather than the equinox. This countdown tracks the exact time remaining until that 1 March start date.

Autumn brings the first real cooling after summer, generally settled weather that makes it a favourite season for outdoor events and school sport, and it's when Easter usually falls. Mother's Day sits right at the tail end of the season too, in mid-May.

Because this system starts autumn about three weeks ahead of the equinox, the countdown shown here may look earlier than an equinox-based calculator built for the Northern Hemisphere or for astronomical reckoning. That's intentional — it reflects how the season is actually defined and used in Australian forecasting and everyday life.
