. . . you'll miss it!

It?

Why, the Vernal (Spring) Equinox of course!

This is one of only two days in calendar year when every location on Earth experiences 12 hours of sunlight and 12 hours of darkness.

And so begins the six month period where the "days" are long - and the sunlight is "strong". Yes, the Northern Hemisphere experiences more hours of daylight than darkness - and the higher sun produces more concentrated (direct) light. This extra sunny half of the year peaks on June 20 when we experience the maximum number of daylight hours/min. and the strongest sunlight of the year as well.

The Autumnal (Fall) Equinox (9/21) will mark the end of this extra sunny half of the year.

A reminder that the spring and fall equinoxes and summer and winter solstices each occur at an exact moment during Earth's 365.25 day, 65,000 mph orbit around the Sun. The equinoxes are the orbital positions where the tilt of Earth's rotational axis are perpendicular to incoming sunlight - that's as if earth's axis was not tilted, The solstices are the orbital positions where Earth's rotational axis have the maxim tilt toward (Summer Solstice) the Sun or away (Winter Solstice) form the Sun.
