In Sydney (Australia), spring comes alive from September to November.
Most people in Australia consider September 1 the first day of spring. But technically speaking, spring hasn't quite sprung yet. Not if you follow the astronomical calendar, anyway.
In the truest sense, according to this News.com.au article, spring starts on or around September 21 (the date varies by a day or so each year).
This is known as the spring equinox, and it heralds the day when the southern hemisphere receives more sun than the northern hemisphere.
