There are just two occasions of the season once the Earth’s axis is tilted neither toward nor from the sun, producing a "nearly" equal quantity of daylight and darkness whatsoever latitudes. These occasions are known as Equinoxes.
Accordingly, at what season may be the Earth’s axis not tilted either toward or from the sun?
Spring within the Northern Hemisphere begins on March 20 or 21 when Earth is again not tilted toward or from the sun. About this day, referred to as spring equinox, you will find 12 hrs of daylight and 12 hrs of darkness both in hemispheres.
