50 free 40th Birthday trivia questions with answers — trivia quiz, new questions added Aug 2026.
44 free 40th birthday trivia questions with answers. Turning forty in 2026 means you were born in 1986, the year of Chernobyl, Challenger, Top Gun, Halley's Comet, the Hand of God and the Mets' comeback. This quiz is built for a 40th birthday party: forty questions split between the world your guest of honour was born into, the celebrities blowing out the same number of candles this year, and the number forty itself, from Ali Baba's thieves and the forty days of Lent to WD-40, UB40, the Roaring Forties and the ruby wedding. The easy rounds ask which comet swung by in 1986 and what Andy sells in The 40-Year-Old Virgin; the harder ones want the temperature where Fahrenheit and Celsius agree, the country whose name means 'land of forty tribes' and the self-help bestseller that gave us 'life begins at forty'. Read them out over cake or hand the link round the table; every question is multiple choice with an explanation, so nobody has to argue with the quizmaster. Every answer was checked against Wikipedia's articles on the year 1986, the number 40 and the films, bands and events involved, and each question carries the sentence that backs it up. That mix of 1986 and the number forty is exactly what people mean by trivia for 40 year olds: the world they were born into, plus a bit of fun at the number's expense.
