Happy first day of spring 2018! Today we celebrate the end of winter and the coming summer. But first, spring! Here are the funniest memes about this special day that occurs on March 20 in 2018.

In 2018, the spring equinox occurs at 12:15 p.m. EDT in the northern hemisphere. During this time, the sun will move directly over the earth's equator and signal the first day of the astronomical spring, versus the meteorological spring. These are the two ways to measure the seasons: the astronomical way reflects natural phenomena to mark time, while the meteorological way is based on the annual temperature cycle as well as our 12-month calendar.

The meteorological spring begins on March 1, and the meteorological spring always occurs during the vernal equinox, which occurs on March 19, 20, or 21 every year, writes DateAndTime.com. The spring equinox is one of the four seasonal astronomical events that affect the earth. The others include the summer solstice, the autumnal equinox, and the winter solstice.

The summer solstice is always in June and occurs either on June 19, 20, or 21. The autumnal equinox happens in September on the 19, 20, or 21, too. The winter solstice happens on the same dates in December. These times are celebrated throughout the world in various cultures with various holidays. The spring equinox is usually associated with Easter, rabbits, and eggs, the latter being symbols of fertility.

One particular practice most people are familiar with this time of year is dyeing eggs. This tradition may have originated in Iran with Nowruz, the Persian New Year. Nowruz was originally a Zoroastrian holiday before Iran was Islamicized. It is still celebrated in the country and has been celebrated for at least 3,000 years.
