Have you ever heard “it’s the first day of Spring?”, but noticed it seems to change every year? Well, I’ve noticed that people have somehow associated the seasons with fiscal quarters as well. What does this mean? Well, depends on how you look at it.
- winter on December 1.
- spring begins on March 1,
- summer on June 1,
- autumn on September 1, and
This isn’t that different from the astronomical one
- Winter (89 days) begins on 21-22 Dec, the winter solstice,
- Spring (92 days) on 20-21 Mar, the spring equinox,
- Summer (93 days) on 21 June, the summer solstice, and
- Autumn (90 days) on 21-22 Sept, the autumn equinox.
An equinox in astronomy is the event when the Sun can be observed to be directly above the Earth’s equator, occurring around March 20 and September 23 each year. The word equinox derives from the Latin words aequus (equal) and nox (night).
A solstice occurs twice a year, whenever Earth’s axis tilts the most toward or away from the Sun, causing the Sun to be farthest north or south at noon. The name is derived from Latin sol (sun) and sistere (to stand still)
