Hey, Stef —
I was running into some of the issues you mentioned when I tried to put
together the example for @TiddlyTweeter.

Actually, YYYY-MM-DD is processed as a date if it's transcluded directly.
I'm guessing you used the DATE function, which converts TiddlyWiki
timestamps to dates but (somewhat stupidly) doesn't convert dates or
strings in "YYYY-MM-DD" format to dates. (I'll have to fix that.) You can
include the date directly by transcluding, eg. {{!!date}} but be advised
there's a bug where the month is off by one. It's fixed in the Git
repository and I'll release the fix later today.
2.) I created a group of tiddlers with the same tag. (...) Using the "sum"

Yes, it's pretty lame that the only thing you can do with filters at the
moment is sum them (meaning strings like "2015-10-01" can't be meaningfully
included). I'll need to add some more functions to expand the options
there.
I should probably come up with a more intuitive term than "datum" to
describe information "included" via filters, transclusion and variables. I
fear that currently the distinction between these values and literal ones
is a bit unclear.
