In one agenda (personal.org) I have the following entry:

* Anniversaries
:PROPERTIES:
#+CATEGORY: Ann
:END:
%%(org-bbdb-anniversaries-future 3)

This works for BBDB entries that have an anniversary like "1973-06-22"
or "2021-04-91 wedding", but it fails for something like "1998-03-12 %s
created bbdb-anniv.el %d years ago" (from the examples in ol-bbdb.el).

The error message is like:

Bad sexp at line 5 in /home/laza/exobrain/org/personal/personal.org: (let
((entry ) (date '(12 3 1998))) (org-bbdb-anniversaries-future 3))
