How do you handle birthdays?

So I have been thinking of putting important birthdays into my LS workflow. I anyways created a People/* namespace and thought, I just put something like

- Birthday
  SCHEDULED: <1991-07-12 Fri.+1y>

As first block. But that now shows up under “SCHEDULED AND DEADLINE” on the bottom of today’s journal. And that query doesn’t seem to be in graph/logseq/config.edn…

How do you (if at all) handle birthdays in LS?
