'PataCal: a perpetual pataphysical calendar for the Palm


'PataCal provides the current date in the pataphysical calendar. It also allows you to choose the date (in either the pataphysical or the vulgar calendar) that will be displayed.
'PataCal comes in two versions:

is the minimal application displaying the date
also displays the saints (beware some can shock some people). It is only useful for those who read french.
is the desk accessory version of patacal.prc (it requires a separate desk accessory launcher).
The two first share the same identifiers and data structures so it is possible to switch from one to another (but not to have both running on the same machine). The desk accessory have another identifier and can be used separately.

About 'Pataphysics and its calendar

" 'Pataphysics is the science of imaginary solutions, which symbolicaly grants to the outlines, the properties of objects described by their virtualities " (La 'Pataphysique est la science des solutions imaginaires, qui accorde symboliquement aux linéaments les propriétés des objets décrits par leur virtualité)
as it is said in Alfred Jarry, Les gestes et opinions du Dr Faustroll (Gallimard/Poésie).
At least, it might not be science, but it is not gloomy science

'PataCal is based on the fourth edition of the official calendar of 1971 (4th edition) as reproduced in the magazine littéraire n°388 of juin 2000.

Origin: The pataphysical era starts on september 8th, 1873 (1 absolu 1).
Revolution: The pataphysical calendar is made of 13 months of 29 days each. Of these days, the 29th are imaginary days (hunyadis) but the 29th of gidouille and that of gueules in leap years. So the pataphysical years is of 365 (13x28+1) days long (366 on leap years).
Peculiarity: all 13th days are fridays.
