Function of the day:
Anybody seen this before, and knows what it does?
X = (367 * A) - (7 * (A + ((B + 9) \ 12)) \ 4) - 3 * ((A + (B - 9) \ 7) \ 100 + 1) \ 4 + 275 * B \ 9 + C + 1721029
I dug it out from an old Fortran 77 program I wrote in the last millennium to use in a current hobby project.
I am amazed I could figure out how to write it when I were just a sprog!

Day of the week, Easter Sunday ... ?

Sorry - no cigar (but on the right track).

So you changed the variables from Y,M and D to try and confuse people...

My keyboard doesn't have those keys, just X, A, B and C. Everything else just says 'Any key' on it.

The problem with quotes on the internet is that you can never tell if they're genuine

I'd just like a chance to prove that money can't make me happy.

Yup! ...or to be more precise pedantic, Julian day number. The full JD has the time added as a decimal fraction of the day.

I used that a lot in Polymod MANY years ago! An obscure French interpreted Basic language designed to run on OS/2 - with line numering!

There is a 'short' version:
JD = (367 * Y) - (7 * (Y + (M + 9) \ 12) \ 4) + (275 * M \ 9) + D + 1721014
This only handles dates back to March 1900, whereas the first one goes back nearly five Millennia.

That's good to know if - for some reason - Microsoft should decide to remove the support for the DateTime data type in .NET!

Fine - but don't forget that a Julian Day starts at 12:00:00 (noon) GMT! 
|
|

Thats fine. For me, in an ideal world, ANY day would start at (or around) noon...

Looks like a date to Julian # conversion for say, starting at 1/1/1901 (maybe) but that's just a WAG.
[edit] - hey, I was right! And I didn't look at the other answers first! [/edit]

You're really, really late - by six thousand, six hundred and twelve years. 
Start date is 12:00:00 on January first 4713 BC.

He was a famous organist, and has played with many great jazzmen. Eddy Louiss left us.
Amongst all his work are two great albums I often listen to : a duo with Michel Petrucciani, "Conférence de presse", and an album with a bunch of great musicians : "Multicolor Feeling Fanfare".
I'll miss him.

That was the inspiration behind NTNON's. As an aside, I have purchased a new Torque Wrench and it is marvelous; Vilmos happy.

They are indeed most useful: I have three, to cover different ranges.

I remember that. No-one seemed to notice that the car that crashed was a Vauxhall, not a Fiat!
