Do someone know about any app for me?...I don't want hear no, because
if i'll hear no, i'll need to write some :)
Several options come to mind:
calcurse (http://culot.org/calcurse/)
pal (http://palcal.sourceforge.net/)
wyrd (http://www.eecs.umich.edu/~pelzlpj/wyrd/) running on top of remind
(http://www.roaringpenguin.com/penguin/open_source_remind.php)
Those three are all ncurses based. (wyrd is a ncurses front-end to
remind. There are other possible front-ends for the remind core, too.)
For X, there's xcal and xcalendar. (I don't have URLs for those.)
I don't know what distribution you're using. All of the above are
available in Debian, and are presumably packaged for other distros, too.
