In ML it's called daysdif or days252bus. Octave doesn't have them AFAIK.

You could have a look in the Financial package:

http://octave.sourceforge.net/financial/overview.html#Time

There are some functions listed there you could use to make the required
functions yourself. In particular, isbusday() has been implemented (I never
used it but it seems indispensable for what you want). 

As to reliability, I don't know - you'll have to check yourself. Some
examples:

isbusday (today())  ## (where today = July 4th, 2012) correctly (for US
citizens) yields: 
ans = 0

datestr (busdate (today))
ans = 05-Jul-2012

...so it seems to work.

Have fun with it,

Philip
