(no subject)
I played a solid 50 minutes of indoor soccer today during a pick-up game on my lunch break. I haven't touched a soccer ball or ran like that for about three years. I didn't even puke!! The co-worker I went with calls me "Mad Dog" for some odd reason and said me puking after soccer didn't fit the "Mad Dog persona". It's happened before, but I held it in today. I have a sore knee and a bloody toe nail, though.
I had a discussion about five minutes ago with a reporter about how the date of Easter is figured out. I had no idea at all. Here it is from the U.S. Naval Observatory web site:
Computing the Date of Easter
The rule is that Easter is the first Sunday after the first ecclesiastical full moon that occurs on or after March 21. The lunar cycles used by the ecclesiastical system are simple to program. The following algorithm will compute the date of Easter in the Gregorian Calendar system.
Please note the following: This is an integer calculation. All variables are integers and all remainders from division are dropped.
The algorithm uses the year, y, to give the month, m, and day, d, of Easter. The symbol * means multiply.
c = y / 100
n = y - 19 * ( y / 19 )
k = ( c - 17 ) / 25
i = c - c / 4 - ( c - k ) / 3 + 19 * n + 15
i = i - 30 * ( i / 30 )
i = i - ( i / 28 ) * ( 1 - ( i / 28 ) * ( 29 / ( i + 1 ) )
* ( ( 21 - n ) / 11 ) )
j = y + y / 4 + i + 2 - c + c / 4
j = j - 7 * ( j / 7 )
l = i - j
m = 3 + ( l + 40 ) / 44
d = l + 28 - 31 * ( m / 4 )
For example, using the year 2010,
y=2010,
c=2010/100=20,
n=2010 - 19 x (2010/19) = 15,
etc. resulting in Easter on April 4, 2010.
