Neither of these show up on my calendar, however a much older contact with a July birthday does. I have tried closing an reopening Kontact to know effect. I have also tried restarting Akonadi. Reproducible: Always Steps to Reproduce: Add birthday to existing contact Actual Results: Calendar is unchanged Expected Results: Calendar shows new birthday I have a directory based vCard address book
In korg 4.6., birthdays are working. Please try it.
