Pi Day Nerdle Puzzles

March 14 written month-first is 3/14 — the first three digits of π — and what began as physicist Larry Shaw's 1988 Exploratorium party is now UNESCO's International Day of Mathematics. A day honouring a mathematical constant deserves an equation puzzle; miss it and Pi Approximation Day, July 22 (22/7, the classic fraction for π), offers a second chance. Below is every year of the archive, each linking to that date’s puzzles.

Frequently Asked Questions#

What date is Pi Day this year?

Pi Day falls on 14 March 2026 in 2026.

Is there a Nerdle answer for every Pi Day?

Only from 2022 onward. Nerdle published its first Classic puzzle on 20 January 2022, so earlier years have a NerdleBuddy puzzle for the date but no Classic answer.

Are the NerdleBuddy puzzles the same as Nerdle's?

No. A NerdleBuddy puzzle is an original equation assigned to that date, with its own play and result history. The Classic answer is Nerdle's own published puzzle for the same day.
