How many days until summer?

Meteorological summer in Australia begins on 1 December and runs through to the end of February — a fixed, calendar-based definition rather than one tied to the solstice, which is how most Australian forecasters, and this countdown, mark the change of season.

Summer here means Christmas, cricket Test matches, beach days, and daylight saving in the states that observe it, stretching evenings out well past eight o'clock. It's also bushfire season across much of the country, and the period when water safety and sun protection messaging ramps up heavily in the media.

Because summer starts a full three weeks before the December solstice under this system, this countdown often reads differently from what solstice-based sources overseas suggest — deliberately so. It reflects how the season is actually defined and used in Australian daily life, from school terms to seasonal retail.
