Programmer's Challange - CH Ting
"We haven't done a programmer's challenge for a long time. How about tackling this one for the morning session in our April meeting?"

Programmer's Challenge: When did Jesus actually die?
  1. He died on a Friday.
  2. The Thursday before his death was Passover, which is the 14th day of 1st month on Jewish calender.
  3. Passover occurs on the first full moon after the Spring equinox.
  4. This year Passover was Monday 3/29/2010.
  5. This year the Spring equinox was Sunday 3/21/2010.
  6. A year has 365.256363 days.
  7. A month has 29.530689 days.

"Which year around 30 AD had Passover on a Thursday?"

"Both integer and floating point math are acceptable, but you will need six decimal digit precision."

"Go figure. Let's compare notes in the morning session. Bring and show your code."
