I used to be able to see friends' birthdays in the right panel of my homepage. But now all I get is the minifeed and ads. And this isn't because none of my friends are celebrating today; If I click events I see that 3 friends were born on this day some years ago.
It appears I am not the only user (still) experiencing this issue. Here's a not very helpful help thread at Facebook.
Why did birthdays get buried?
Update (6/21): Birthdays are back for me. This problem seems to have corrected itself.

That's weird! You should be able to see your friends birthdays in the right hand side panel. No changes were made recently that would affect this - friends' birthdays are important to people on FB! If you don't mind, file a bug so the userops team can look into this. Or email me with a scrnshot and I'll pass it along.
