So March 14, or 3/14, is known now as Pi Day. Why do we equate 3.14 as 3-14 or 3/14? Because it’s cute.
But let’s look at the real numbers, shall we? If you convert 3.1415926 to real dates, you might look at the Gregorian calendar, or, if you’re a nerd like me, Unix timestamps.
Starting on January 1, 1970, the clock started. The timestamp is measured in seconds, the number 60 equates to 60 seconds after January 1, 1970, 00:00:00. Which would be 12:01:00 AM.
3.1415926 seconds would then be 12:00:03 AM, since we have to round. (The timestamp is in integers.) So the first Pi day is January 1, 1970.
Now let’s move that decimal place. Why? Because this whole thing is arbitrary, that’s why.
31.415926 is a mere 31 seconds after the start, so the second Pi day is ALSO January 1, 1970. Same with the third – 314.15926 was about 5 minutes into the Unix epoch. 52 minutes after the hour we hit the fourth Pi day. Sometime after 8AM on January 1, 1970, we hit the fifth Pi day.
The SIXTH Pi day, 314159.26, comes on a different day — January 3rd, 1970.
February 5th, 1970, is our 7th Pi day.
Then we jump all the way to December 29th, 1970. I guess 1970 was a good year for Pi. Eight Pi days! Glad we didn’t have Twitter back then.
Our next jump is all the way to 1979 – on December 16, we hit 314159265 seconds into the Unix epoch. Also the first one I was alive for.
The 10th Pi day, however, still hasn’t arrived. It won’t be hear until 2069, on July 21.
Until then, maybe you can stop tweeting about Pi day.
(Don’t get me started about May the Fourth.)
