How can I find all the birthdays and anniversaries that occur this month for my contacts? I tried searching the Contacts folder but got no results.
You need to search the Calendar folder, not the Contacts folder. The contact stores the original date, not this year's occurrence.
Switch to the Calendar folder, and select Tools, Advanced Find. In the Search for the word(s) text box, type birthday or anniversary. Switch to the Advanced tab, and type start in the Field text box. From the Condition drop-down list, choose this month, then click Add to List. Click Find Now, and you should get a list of all the birthdays and anniversaries that occur this month.
