Why Has the Date Changed for Start of Spring? URL: http://www.space.com/spacewatch/050318_equinox.html Description: This article describes that while the first day of spring in the Northern Hemisphere traditionally has been celebrated as March 21, the vernal equinox has "landed on March 21, only 36 out of 100 years [during the 20th century]. And from 1981 to 2102, Americans will celebrate the first day of spring no later than March 20." Explains reasons why seasonal dates can vary from year to year. From Space.com.
