What is International Pi Day?
Pi Day is an annual celebration of the mathematical constant π (pi). It is observed on March 14 since 3, 1, and 4 are the first three significant digits of π. It's also Albert Einstein's birthday!
How to celebrate
Mark the day with a poster made in Dayfeed — pick your favourite photo as the background, share it to your story or group chat, and set a reminder so you never miss it next year.
