The vernal equinox is coming this Thursday, March 19. Yes, you heard that right, on the 19th, not the 20th or 21st like it is most years. In fact, this is the earliest Vernal Equinox since 1894, meaning the earliest in all of our lifetimes. Although the equinox is on the 19th this year, it only is in parts of the western Hemisphere as the official time the direct rays of the sun are over the equator is 11:50 PM eastern daylight time, meaning 10:50 central time, so it missed out on being on the 20th by just a bit. Because some calendars use Greenwich Mean time to mark the date of equinoxes and solstices, your calendar may say the 20th, but in our time zones it will be late Thursday.
