Many around the world spent today celebrating the widest known mathematical constant, that share’s it’s name with a tasty treat:
The celebrate today because as March 14, or 3.14, it is a representation of ?.
However this is wrong.
We could consider a year to be like a circle, in that at the end (December) it connects right back to the start (January). In this representation we could represent the total number of days in a year (365.25) equal to the total angle of a circle (360 degrees, or 2? radians). This system would make “pi-day” to be approximately June 1st (or 2nd on a leap year, which also helps deal with rounding errors). This would also give us a 2? day on New Year’s Eve.
Or perhaps we should use the year’s total number of days as a base of counting, in which case ? would have to be converted to that base and that would be the date. (Check my math perhaps) I think this date works out to April 24th or 25th (depending on leap years again).
However, explaining to people why you’re calling April 25th, or June 1st pi day and eating pie (which I did indulge in today), might take longer than the brief amusement provided by the idea.
