Pi Approximation
Day
Pi = Circle's circumference
/ Ciccle's diameter
Depends
on Date Format
People in countries that write
their dates in the date/ month
format celebrate Pi Approximation
or Casual Pi Day on 22 July
or 22/7. On the other hand,
those who write their date in
month/ date format celebrate
Pi Day on March 14 (3/14 or
3-14) because the first three
digits of the date correspond
to the first three digits of
pi - 3.14.
Move
to Replace Pi
In recent years, some mathematicians
and physicists have argued for
the replacement of the π by
tau and to celebrate Tau Day
on June 28 instead of celebrating
Pi Day or Pi Approximation Day.
