The first day of spring when the planet is balance equally between daylight and darkness.

Or as described by the US Naval Observatory:

On the day of an equinox, the geometric center of the Sun’s disk crosses the equator, and this point is above the horizon for 12 hours everywhere on the Earth. However, the Sun is not simply a geometric point. Sunrise is defined as the instant when the leading edge of the Sun’s disk becomes visible on the horizon, whereas sunset is the instant when the trailing edge of the disk disappears below the horizon. These are the moments of first and last direct sunlight. At these times the center of the disk is below the horizon. Furthermore, atmospheric refraction causes the Sun’s disk to appear higher in the sky than it would if the Earth had no atmosphere.

I figured I would kick off the new season, the promise of rebirth, with drawings of various spring outfiits I found while roaming around tumblr.
