birthday

[meomuopcon]

to ask someone's birthday, we use:
- what's your birthday?
- What date is your birthday?
- What's your date of birth?
- when is your birthday?
which one is wrong?
thanks

Grammatically, they are all up to spec, however the form What's your date of birth would be used in a bureaucratic sense (at the IRS, the Department of Motor Vehicles, etc.), or by people who are more interested in your age than buying you a cake!

i don't think so.
What is your birthday? it sounds wrong, doesn't it?
how about " What's the date of your birthday?"

My goodness - how did I overlook that one?! I read it as "When"! Embarrassing!

So, just to clear up my little oversight, here are your possibilities:

When is your birthday?
What date is your birthday?

Sorry - thanks for getting back to me on that one.

Rgs,
Bill

What's the date of your birthday? it is the right question. "the" is determiner for date. when you are borned, that day has just defined. so we should use "the", is it correct?

Either "My birthday is (on) the 14th of April" but "I was born on the 14th of April 1984". Or "My date of birth is 14/4/84".

"On" is not totally necessary in the first sentence.
