Key Differences

Birthdate is a specific term referring to the exact day, month, and often year that someone was born. It's factual and used for official records like identification cards, passports, and legal documents. Birthday, on the other hand, is the celebration of that birthdate each year. The term Birthday typically does not include the year and is more of a social construct for celebration.

In terms of grammar, 'birthdate' is a compound noun that encapsulates the idea of the specific date of birth. Birthday, though also a noun, has a more festive connotation and is often associated with parties, cake, and gifts. Birthdate is a static fact about a person, while a Birthday is an evolving celebration that can be different each year.

Birthdate is often required in formal applications like job forms, academic records, or medical history documents to determine age or identity. In contrast, Birthday is a more casual term that you would find in social settings or event invitations. People may ask for your Birthday to plan a party but would ask for your birthdate for something official.

On a practical level, the birthdate is a constant and doesn't change from year to year. Birthdays, however, can be celebrated in various ways and on different days if the actual date is inconvenient. The birthdate is a milestone set in the past, while the Birthday is a recurring event celebrated in the present.
