Pi Day is an annual celebration of the mathematical constant π (pi). Pi Day is observed on March 14 (3/14 in the month/day format) since 3, 1, and 4 are the first three significant digits of π.
Pii Day is the day that PiiComm team members celebrate and reflect on our combined efforts to be the best we can at what we do, to thank our customers and remind ourselves that spring is just around the corner.
