March 14, 1592 could have been an exciting day, a once in time event. I wonder if anybody noticed

Re: Happy Pi Day, 2018

Mike
If you want answer as to whether Mar 14, 1592 was celebrated as Pi day the answer
is a definite "maybe" though why it would have been celebrated because it was such
a nerdy and elitist piece of knowledge is an open question.  An on article that answers
the question partially is the following:
https://meangreenmath.com/2015/03/12/pi-day-in-1592/

A little history from this article is quoted here:

|My first thought was that \pi may not have been known to that many decimal
|places in 1592. However, a quick check on Wikipedia (see also here), as well
|as the book “\pi Unleashed,” verifies that my initial thought was wrong.
|In China, 7 places of accuracy were obtained by the 5th century.
|By the 14th century, \pi was known to 13 decimal places in India.
|In the 15th century, \pi was calculated to 16 decimal places in Persia.

How many people would have known what Pi was as well as why
it was important?  Plrobably very few.  Today, however, my email from
the journal Proceeding of the National Academy of Sciences boldly
acknowledges Pi Day in it Subject line.  And so does the electronics
dealer NewEgg, as well as the makers of Mathematica that have sent
to two emails on their special discounts on the home and student versions
of Matlab, good to the end of the month, and other sources that I have
deleted.  So, if you have mathy/sciency connections, you're little to get
a bunch of reminders that today is Pi day -- how many folks outside of
this group would know it?  Or are they more concerned with the election
in Texas (the democrat won in a congreesional district that was Trump
won with +20 more votes) or that Stephen Hawking has dies or what is
the fallout of the "The Bachelor" show or whatever the hell the Kardashians
are doing (outside of watching the new O.J. video) and so on.

I don't know how exciting Mar 14, 1592 could have been (though
there seems to be some celebrations on Mar 15).. A more interesting
intellectual question, perhaps, is does one use the Julian or Gregorian
calendar in reckoning the date.  Quoting the Wikipedia on the year "1592":

|1592 was a leap year starting on Wednesday of the Gregorian calendar
|and a leap year starting on Saturday of the Julian calendar, the 1592nd
|year of the Common Era (CE) and Anno Domini (AD) designations, the
|592nd year of the 2nd millennium, the 92nd year of the 16th century, and
|the 3rd year of the 1590s decade. As of the start of 1592, the Gregorian
|calendar was 10 days ahead of the Julian calendar, which remained in
|localized use until 1923

The Gregorian calendar date for Pi day is what we use today (as mentioned
in the Wiki entry) but what about those following the Gregorian calendar
(which most Orthodox Christians followed and still follow).  And what about
the Jewish calendar?  Pi day comes way too early.  Similarly, I believe for
Chinese and the Indians.  And what about the Mayans, eh?  A lot of confusion,
I think for Mar 14, 1592.  I think most folks would be satisfied with celebrating
4/20 whenever possible. ;-)
