$ cal 5875707
cal: year 5875707 not in range 1..5875706

What is the significance of the year 5875706? Why stop there? This seems like some kind of RMS Michael Shuttleworth ploy to fuck us over in the calendar department.

5875706 = 2 × 2937853
5875707 = 3 × 1958569

Seems pretty obvious to me.

Our god, RMS MS S, has decided that there will be no year 5875707, because 5875706 is when GPL v3 will expire.

I just tried this on FreeBSD, OS X, and Linux (with util-linux-ng), and they all restrict the dates to 1-9999. What version of cal are you using?

I tried it on Debian and Ubanto and they both give 5875706

Name: Anonymous 2008-12-17 23:52

Is cal even GUN? It's part of a package called "bsdmainutils" on the Ubanto repositories.

Your variable names suck. ax? dx? These are good register names, but when we program in higher level languages you can use words that mean something. Try it sometime.

Yes, but which cal are you using? As I said, mine is "util-linux-ng". Obviously, yours is not. Where did it come from? Could you please provide a link to the source or something?

The cal utility shall write a calendar to standard output using the Julian calendar for dates from January 1, 1 through September 2, 1752 and the Gregorian calendar for dates from September 14, 1752 through December 31, 9999 as though the Gregorian calendar had been adopted on September 14, 1752.
9999 is the STANDARD!!!

Why don't all these small programs just use a bignum library for all of their integers? It's not like it'll affect performance.

Heck, write them in Python. That WILL affect performance though.

I just want to point out that the one you wrote broken, and the fixed one won't work for anonix (or the fix will do nothing).
according to them it's not broken:
- No internationalization. A large amount of GNU bloat is caused by this, and
with English continuing to dominate, the ANONIX initial planning group decided
against explicitly adding code for this, instead opting to let those  few who
need it translate themselves.

I don't want to fix it, I have my own working from gnu.
your gnu one can't do cal 1 340282366920938463463374607431768211456, while this one can (and supports localization):

wow, that's actually a bug! the stuff after the last && should be in parentheses.

the ' ' doesn't do anything, but it doesn't hurt anything either.

ok, the first one isn't used, but that doesn't hurt anything.
