Now that it is 2000, the 1997 date which was the original question I answered back in 1997, is no longer interesting, so I have updated this question with information on the next few years equinox dates and times. Here is a short list of the Vernal Equinox dates and times from 1999-2019. For Central Standard Time, subtract one hour from the Eastern Standard Time (EST) time given in column 9 below.
