The Vernal, or Spring equinox occurs today at 1006 PM CDT. It’s a common misconception that that daylight and nighttime hours are equal on the Fall/Spring equinoxes. In fact, there are a few more minutes of daylight. This is because the “top” edge of the sun peeks above the horizon several minutes before, and dips below the horizon several minutes after the geometric center does! Refraction of light through the atmosphere also adds a little extra daytime.
