Find day of week from month and year

[Laguna]

Hi Gurus,

I want to find the expiration date of stock options (3rd Friday of the
month) for an any give month and year. I have tried a few tricks with
the functions provided by the built-in module time, but the problem was
that the 9 element tuple need to be populated correctly. Can anyone
help me out on this one?

Thanks a bunch,
Laguna

Requirements:

d0 = expiration(9, 2005) # d0 would be 16
d1 = expiration(6, 2003) # d1 would be 20
d2 = expiration(2, 2006) # d2 would be 17
