Do you know why Spring occurs when it does and that the reason for the season is actually scientific, since the Earth rotates on an axis that is tilted in it's orbit.
In the southern hemisphere at this time of year, they would be experiencing the Autumnal (Fall) Equinox. Conversely, we would experience the Autumnal Equinox in September, and the southern hemisphere would experience the Vernal Equinox of course.
From here on in, we begin to see longer and longer daylight hours until we reach the Summer Solstice, which is the peak amount of sunlight in our northern hemisphere.
Of course, we all know that long stretch of darkness at the Winter Solstice, where it gets dark around 4:00 in the afternoon and the sun doesn't arise until 8:30, and that's just around Calgary. Worse as you get into the far north where it stays dark all day. Naturally, the opposite is true wen they get 24 hours of sunlight on the occasion of the Summer Solstice, hence the term "Land Of The Midnight Sun".
