The April Perl challenge by Ramana Mokkapati

THE CHALLENGE:



π (PIE) is conjectured to be a "Normal" number, which means, it contains all finite strings in its expansion.
That means, under appropriate encoding, entire universe (all events, pictures, videos, all books/music ever produced
in the past or will be produced in future is all in there!!!

 
The following website allows us to query strings in π up to 200M digits in the expansion. http://www.angio.net/pi/piquery.html

All birthdays in 2015 can be represented in format 2015MMDD

E.g. The 4th July 2015 is represented by string 20150704 occurs at position 86,897,846  counting from the first digit after the decimal point

Challenge: Among 365 days in the year 2015, find all days that do not figure in the 200M digits of  π
