45 Birthday Trivia Questions and Answers, Ready to Use

Good birthday trivia needs two different kinds of questions: personal ones, which require sourcing real answers from people who know the birthday person, and general-knowledge ones, which come with fixed, checkable answers you can use straight away. Below are 45 questions split that way, with a working answer key for the general round and a short method for sourcing the personal round.

How do you source answers for personal trivia in advance?

You can't guess these — you have to ask. Two weeks before the party:

1. Message the inner circle. Partner, best friend, sibling, one parent. Ask each for three to five facts: first job, first car, a nickname and its origin, an embarrassing moment they'll allow you to use, and one thing the birthday person is stubbornly proud of.
2. Cross-check. If two sources disagree on a detail (a common one: "how did they meet their partner"), ask the birthday person's partner directly — they're usually the tie-breaker.
3. Write the question before you have the answer. "What was [name]'s first job?" is a fine question regardless of what the answer turns out to be. Fill in the answer once it comes back.

If the birthday person is in a family or friend WhatsApp group with years of history, skip the manual sourcing entirely: upload the export to WhatsQuiz and it pulls specific, verifiable moments — actual quotes, actual dates, actual running jokes — straight from the conversation, with answers already attached.
