Today is also called the vernal equinox. That means that the hours of sunlight equal the hours of nighttime.
The amount of sunlight increases consistently until the longest day of the year-Summer Solstice. Then the hours of daylight slowly decrease until they equal the night hours at the autumnal equinox.
In the Northern Hemisphere, the vernal equinox happens every year on March 20th or 21st. If you’re in the Southern Hemisphere, it falls on September 22nd or 23rd.
Enjoy the run-up to summer! Sonja
