Why Was I Legally Married On February 29th 1992

1. I happened to be getting married in 1992--this was very much happenstance: Had the first Gulf War not happened, it would have been in 1991.
2. My Wife's parents asked that we be legally married sometime before our planned drive from Washington to Massachusetts.   We were to have the formal ceremony in the Summer, in Massachusetts.
3. We found-out about the above, sometime in late 1991 or very early in 1992.
4. We narrowed the date down to a couple of different weekends.
5. One of which was the last week in February.
6. Leap-Day fell on the Saturday of that weekend.
7. It was probably easier to book the judge for a Saturday than a Sunday, but why would anybody want March 1st (Younger sister's birthday) when you could have February 29th?
