July 22nd:
July 22nd (international numeric date is 22/7/year) is Pi Approximation Day and celebrates the discovery of the calculation of the Math Symbol Pi – which is approximately calculated at 22/7 (22 divided by 7).
Peter Kevin Connell from Today in Heritage History warns:
“Please be courteous driving today and try to avoid all the International Mathematician Parades. Most mathematician marchers generally have problems negotiating traffic while dressed in Rhombus and Trapezoid costumes.”
