I imported from my Access DB my personal address book. There I have a lot of
birthdays and when I imported these contacts (around 1000) in the calendar my
friends and partners are not indexed.

If I enter in a contact and re-type and Save the contact bithdate - then it
appears like reminder in the calendar, but it will be really a long and
senssless idea to re-type all the birthdates in my contacts.

Please, tell me from where in Calendar or in Contacts I could show in the
Calendar my birthdate reminders.
