How Many Of Your Facebook Friends Know Your Actual Birthday?

Outside of my immediate family, I have no idea when anyone’s birthday is without the aid of Facebook. And you probably don’t either. David Plotz at Slate wanted to see what would happen if he celebrated three birthdays in July.

The results were predictable. He got a bunch of wall posts for each of his July birthdays (his actual birthday is in January), with one industrious fellow wishing him a total of four “HBDs”.

So what about you, dear readers: how many of your Facebook friends would notice something was amiss if you started celebrating birthdays every few weeks, half a year removed from your actual birthday? [Slate]

    I did this a little while ago. My birthday is in September, but I had one in March. I had over 140 wallposts wishing me happy birthday; my entire list is only 243.

    Admittedly, I know maybe 10 friends birthdays without Facebook, and that itself is aided by two December 10′s and one December 12.

    I generally have a rule with facebook friends birthdays; if I didn’t know them before, I don’t post on their wall/send message/etc. but I’m a complete grinch with birthdays and holidays..

    I don’t have my birthday as part of my Facebook profile and I record the birthdays of people I care about in my calendar(s). Although I’ll send a FB “HBD” message when I see their birthday come up, I’ll typically have already sent an SMS or MMS that morning.

    I didn’t have my birthday one year and no one wished me a happy birthday.
    I added it last year and I got close to 10.
    My list is around 300.

    Says a lot about my life, lol.
