You should never put your real actual birthday nor age anywhere online, it becomes merged with other data about you and can used for identity theft. For example some banks use your DoB as proof of who you are, if you happened to also know say the last 4 digits of your SSN then they pretty much can do what they like.
I have a typical joke birthday in my profile.
And everyone I touch digitally I tell them the same.
To your question, when the date I put in the profile came up, no gifts.
