Learn English – “Birthday” vs “Date of birth” on a website form

word-choice

In a login form for a website, what expression would fit better for the date input field? Birthday or Date of Birth?

And why?

Best Answer

In everyday language "birthday" is associated more with the anniversary of the date of birth. When asked about it, a person may (or would likely) provide just the month and day, but not the year.

"Date of birth", however, is much more difficult to misinterpret.

Whether to capitalize "birth" in your User Interface is probably up to your UX designers.
