undocumented date addition/subtraction operators

I just realized why the attached and variants are FAQs --- the operators
for date minus date, date plus integer, etc are documented nowhere.

Will fix.

Hi,
is there an easy way to get the Difference between 2 dates in Days... as
an integer?

age('date1','date2') results in  x years y days or something similar.
but I would like to
have the result in number of days as an integer.

Thanks for your help

Alex
