Calendar--how do I stop it from showing birthdays? I have 7,000 people on Facebook, and that many birthday notices drowns everything else. How do I turn the feature off? NO MORE BIRTHDAYS...

All my birthdays have been imported from my contacts to my calendar, which is fine, but I do not see a setting where I can mark them private? Also, reading the other questions, it isn't entirely clear to me who can see my calendar entries that are not marked private. If I do not share my calendar with anyone, can other people access it?

Thanks!

i have tried multiple different computers, operating systems and browsers.  how do I delete my calendars on my outlook.com account?  I would like to delete my birthday calendar and US holidays calendar and all entries on those calendars.  I cant even do it manually as when I try to delete any birthday entry I get this message:

 

Calendar error
Sorry, there’s a problem deleting this birthday right now. Please try again later.
 
All contacts have already been deleted from the account.
 
thanks for your help.
All my birthdays were entered into my calendar.  All of a sudden, all of the birthdays are gone off my iPhone but there is a new color coded category for birthdays.  It is incomplete and, at times, wrong.  How do I get my calendar entries back without having to retype them all?  I checked calendar.live and they were not there either.  I did not make any changes to this account.  To be honest, I was not even aware there was a category for birthdays and had been saving everything to the calendar.  Thanks.
Hi,

I am a WP8 user (NL 620). This morning I was adding a list of to-do tasks in my calendar but after saving the tasks I noticed that all my Facebook birthdays had disappeared from the calendar. The events were still there but the birthdays were gone.

I have soft-reset my phone twice. I have also tried deleting and syncing my facebook account, twice, but to no avail. I have tried going to the outlook.com and managed my facebook connection from there too, but my facebook birthdays just won't show up.

Please help me out.
I have gone into the settings for my calendar and switched the button for birthdays to hide, but they are still there. I don't want to completely take Facebook off of my PC but I really need those birthdays off of there because I'd like to use it for school work and work schedules. 
I have birthdays set in my calander and would like to set a notice of these dates 4 days in advance. How do i do this?
I have shared my calendar with my boss. Now she sees everything on my calendar, even the us holidays, and contacts birthdays, stuff she doesn't really need to see. How can i set it to show only works stuff?

Thanks,
Pyro
Why are birthdays listed one day early?
