Most phrases can be understood by thinking about what each word means. Invalid means false, inaccurate. Birthday is the date of a person's birth. The phrase "invalid birthday" would most likely be seen on the Internet, on websites that ask a User to enter a birth date. Web designers often use the least words to make their statement.
