Enjoy 16 long day light hours.

Okay, most people know this one. Earth orbits around the sun on a tilted axis (probably because our planet collided with some other massive object billions of years ago, back when it was still being formed).

So between March and September, Earth’s Northern Hemisphere gets more exposure to direct sunlight over the course of a day. The rest of the year, the Southern Hemisphere gets more. It’s the reason for the seasons:

In the Northern Hemisphere, “peak” sunlight usually occurs on June 20, 21, or 22 of any given year. That’s the summer solstice.
By contrast, the Southern Hemisphere reaches peak sunlight on December 21, 22, or 23 and the north hits peak darkness — that’s our winter solstice.

For astrologists, the summer solstice marks the beginning of summer. The winter solstice announces the start of winter, with equinoxes in March and September heralding the start of Spring and Autumn. Meteorologists use a different system based on the calendar year.
