An Interesting Date

Andrew had asked me to calculate a particular date a year or so ago. I did a rough approximation and had planned to figure it out exactly and celebrate it somehow. I wasn't sure exactly what I would do, but I did want to mark it, be aware of the day on the day. Unfortunately I did not calculate the exact date, and I now realize that it slipped past without notice. I just did the math, and it was on or very near March 30, 2007.

What was the significance of the date, you ask? It was the point at which I had been married for exactly half of my life.
