Manager Self Service Team Calendar

hi,

How to items such as birthdays, anniversaries appear on the MSS calendar? Is there other set up involved other than the Custom Events (see Team Calendar Technical Brief) for birthdays etc?

I understand from my research that items such as absences appear on the calendar due to integration with Absence Management. That being said, how do vacations appear on the MSS calendar? Is this due to integration with Time and Labor?

Thank you very much.
