As A bit of fun with my mates, I'd like to know when special Birthdays
come up.
For Example
1 Billionth second is around the 30-31 year old mark.
21st Martian Years is around the 40th Year old

So basically when i enter a birthday in the contacts form, i'd like
outlook to calculate the days for certain anniversaries, and create all
day events for them.

I have the formulas for calculating the special birthdays, Anyone have
any ideas on How to Get Outlook to Create the relevant meetings?

I'm suspecting it will require some coding, Has anyone tried something
like this or similar

Thanks
