Anniversaries are a great way into history, but "on this day" lists often stop at the headline. Each event here adds a detective question: who wrote the source, when, and what might they have left out or tidied up?

There are 37 well-documented dates across 2,000 years, including Caesar, Hastings, Magna Carta, the Titanic, D-Day and Apollo 11. Teachers can use them as five-minute starters, and they're great at the dinner table.
