I'm trying to come up with a better way to give myself advanced notice on some peoples' birthdays coming up. 

Right now, I use the following in a `cal.org` file to give me notice in agenda that birthdays are coming up:

```

* BDays                                                                         :bday:
%%(org-contacts-anniversaries "BIRTHDAY")

```

The generally feeds off a `contacts.org` entry of the nature:

```

*** John Wick                                                  

:PROPERTIES:
:EMAIL: therealjdub@notthepuppy.com
:BIRTHDAY: 1975-06-06
:END:

```

What I'd like is to get, on virtually all birthdays , a week's notice through due soon (which I'll sort out in org-super-agenda in the view). Alternatively, is there a nicer way to tag or otherwise note some birthdays in the `contacts.org` so that I could note special people (close friends, family, etc) where I could set a specific advanced notice period so that I have time to do something special for them etc?

Would love to hear peoples' approaches to this. In general, if I'm not looking out 2 weeks ahead (I spend most time in the day view), I can get surprised.

thanks!

Daryl.
