G.1.1 Exclusions with date argument %?[date] special texts

G.1.1.1 Inclusive date period %i[date][#[date]] special text  
G.1.1.2 Exclusive date period %e[date][#[date]] special text  

First of all, an inclusive date period %?[date] special text can be specified with the effect, that only those fixed dates are respected and displayed which are part of this period. And the specification of an exclusive date period %?[date] special text has the effect, that only those fixed dates are respected and displayed which are not part of this period.

Cleverly combined, these special texts offer very effective filtration capabilities used for the definition of special periods in a highly flexible manner, for example:

 
0*d1#999 Every day of year: from January...August except April\
         %i00001#00008 %e00004#00004
;
0*d1#999 Every day of year: from 1991...1993 and from 1996\
         except February 1992 and all September\
         %i1991#1993 %i1996# %e19922#19922 %e00009#00009
