I think that is a lovely gesture!  I would certainly appreciate it and I know some people who have no one to remember their special day!   I would simply ask them their star sign and then when they say Libra I would say, my sister is a Libra too - what date is your birthday??

Good luck and let us know what you decide upon!

Oh, John by the way, I'm updating all of my contacts and for some reason I don't have your birthday.

I would do some kind of registration form asking for the birthday.

With all the identity theft going on, I wouldn't go out of my way to advertise my birth date. Also, many people ( including me) hate it when someone tries to give me a gift. I wouldn't use deceitful tactics to try to obtain people's birthdates. Another thing to consider if you want to give people gifts is, why does it have to be on their birthday. You could give people, " thanks for your business" gifts on any day of the year. It could be on the anniversay of their closing, etc.

I am updating my data base and I noticed that we have overlooked your birthday.

Just ask. Do not waste time on searching it online. I would tell you. Especially, because you are going to bring a small gift:)

For security reasons, I don't give out my birthday (the real one) to anyone but family and close friends and certainly not on social media sites. Facebook comes to mind where lots of people send me birthday wishes on my non-birthday. I don't know, somehow it's creepy for my vendors to send me birthday cards and presents. Sorry, for some reason I feel strongly about this maybe because birthdays were always close family affairs. Now everything is so commercialized.

Jennifer Provencio I usually know their birthday - either on G+, LinkedIn or on Facebook!

And if I don't, I ask directly. 'I am Gemini, what sun sign is yours? And what date?' Usually, people share it willingly.

Depends on my relationship with the lender.  One I'd worked with I'd answer. Random lender asking the questions I'd tell to go pound sand.

What a great idea. I would love this. There are some great suggestions below. 

I often look on FB...even if not listed in their "about" portion, if they have their updates public, you can usually scan or search for their birthday as others wish them happy birthday. Then I go to G+ as that sometimes has a few more.

for one brokerage that I knew well, I just asked the team leader for the list of birthdays.

Just tell them you are filling out their profile and would like to have all of the important info for the people you care about.

You could always just ask...or you can say so and so has a birthday this month, when is yours?  I usually let them know that I keep in touch and would like to know their birthday so I can send them a card.

My birthday is 8/21. I usually send birthday wishes to my Facebook friends. The list automatically appears each day. If they do not post their birth date, they will not receive a message from me. 

Everybody likes to be remembered on their special days.

Of course you know, and I know, the question is very transparent regarding your intentions. Your intent is to do the FACEBOOK thing and cause great interruption to the agent on that day, along with 21 restaurants, (for them I've offered six different birthdays) 111 Facebook respondees, office staff, and a plethora of folks who collected the same date and have every intent of sending a mindless greeting.

Is that what you REALLY want to do?

Why not just remember the day you met and the attributes of character that impressed you? 

But if you must, simply ask, 'When does your mother send your birthday card?" There will be a story, but the info you want will be revealed.
