Via {(ftime fmt="%Y")} you can get the year.
Via {(ftime fmt="%j")} you can get the day of the year.
WikiSh (set ...) and MarkupExpressionsExtensions (math ...) and
MarkupExprPlus (add/mult/etc ...) and perhaps others (?) give the capability
of simple math. Here's how it would look in WikiSh:
Date: 2008-03-05
Apptmt: Lunch with Sam
{(set -q xnow = (ftime fmt="%Y") * 365)}
{(set -q xthen = (ftime fmt="%Y" when={$:Date}) * 365)}
{(set -q ynow = (ftime fmt="%j"))}
{(set -q ythen = (ftime fmt="%j" when={$:Date}))}
{(set -q diff = $xthen + $ythen - $xnow - $ynow)}
{(echo "Don't forget your appointment ({$:Apptmt}) in $diff days")}
Technically you should be able to do all this in a single (set ...) call but
somehow the (ftime ...) is not interacting well with (set ...) so each set
that involves (ftime ...) has to be done individually. I'll figure that out
later, but for now this does work. You can probably get it working with
some of the other packages (mentioned above) as well...
