Equinox

In News
  • March 20 marks the end of winter in northern and summer in southern hemisphere.
About Equinox
  • The word equinox is derived from two Latin words – aequus (equal) and nox (night).
  • There are only two times of the year when the Earth’s axis is tilted neither toward nor away from the sun, which results in a nearly equal amount of daylight and darkness at all latitudes. These events are referred to as Equinoxes.
  • The equinoxes happen in March (about March 21) and September (about September 23) on these days the Sun is exactly above the Equator
  • The equator and places near the equator experience nearly 12 hours of the day and 12 hours of the night.
Reasons
  • The phenomenon occurs due to the Earth’s axial tilt, or the angle by which the planet is tilted relative to the Sun.
  • The imaginary axis of our planet is not straight up and down but is tilted by 23.5 degrees.
  • This is why different regions of the Earth experience different measures of sunlight.
