This Friday, November 22, 2013, marks
the 50th anniversary of JFK’s death.
On this special occasion, I dedicate these
next few slides to the memory of JFK.

Three Consecutive Primes Lead
to JFK’s Birthday
JFK’s birthday can be constructed
from three consecutive prime
numbers, 17, 19 and 23. How?
5291917 = (23 x 23) 1917

JFK’s and RFK’s Birthdays Have a Unique
Numerical Connection
JFK’s and RFK’s birthdays have a special
numerical connection. How?
The reverse of the leftmost four digits of
JFK’s birthday equals the rightmost four
digits of RFK’s birthday.
JFK’s Birthday: 5291917
RFK’s Birthday: 11201925

JFK’s Last Name, Kennedy
• If numbers are assigned to the letters of the English alphabet in
alphabetical order (A = 1, B = 2, etc.), the numbers assigned to
the letters of “Kennedy” add up to 78.
• If 78 is split as 7 and 8, the seventh and eighth primes (17 and
19) put side by side yield JFK’s birth year, 1917.
• 7 + 8 = 3 x 5 where digits 3 and 5 side by side give 35. JFK served
as the 35th US President.
• 7 + 8 = 9 + 6 where 9 and 6 put side by side make 96, JFK’s age
today.
• 78 = 3 x 26 where 3 and 26 side by side yield 326. JFK got killed
on the 326th day of 1963.
• 7 + 8 = 15 where 15th prime number is 47, which equals to the
sum of the numbers assigned to JFK’s first name, “John”.

JFK’s Birth and Death Dates
• JFK’s full birthday is 5291917.
• The sum of the squares of the digits of 5291917 yield 242.
Twice 242 equals square of 22 and half of 242 is square of 11.
Numbers 11 and 22 put side by side make 1122, representing
November 22, the day JFK was assassinated in 1963.
• The sum of the cubes of the digits of 5291917 yields 1936,
which by switching its rightmost two digits, results in 1963, the
year JFK was killed. Also, the square root of 1936 is 44, which
equals the difference of 19 and 63, which make up 1963.
• If the digits of 11221963 (the day JFK was shot) are numbered
left to right from 1 to 8, the odd-numbered digits put side by
side yield 1216, which equals four times 304. Interestingly
enough, 304 = 50 + 92 + 91 + 71, where switching the digits of
these four two-digit numbers and putting them side by side
yield 05291917!

JFK’s Birth Year
• If JFK’s birth year 1917 is split into two numbers
consisting of its odd- and even-numbered digits
as 11 and 97, these two numbers add up to 108.
Coincidentally, the numbers assigned to the
letters of JFK’s middle name, “Fitzgerald”, also
add up to 108.
• The numbers assigned to the letters of JFK add
up to 27. Multiplying 27 with one less than its
reverse (72) yields JFK’s birth year, 1917.

JFK’s 46th Birthday
• JFK died 177 days after his 46th birthday, 5291963.
The digits of 5291963 add up to 35, signifying JFK’s
35th US Presidency.
• 1 + 7 + 7 = 15 = 3 x 5, where again, 3 and 5 side by
side make 35.
• 177 = 3 x 59, where 59 equals the sum of the three
consecutive primes (17, 19, and 23) which constitute
JFK’s birthday, 5291917.
• Also, if 177 is split as 1 and 77, 1 + 77 = 78, the sum of
the numbers assigned to the letters of JFK’s last name,
“Kennedy”.
• In addition, 46 = 23 + 23, where 23 x 23 = 529, JFK’s
birth date, May 29.

JFK Died 2 Days After RFK’s 38th Birthday
• JFK died on 11221963, 2 days after RFK’s 38th
birthday, 11201963. Ironically, 38 divided by 2 is 19,
38 minus 2 is 36, and 19 and reverse of 36 (63) put
side by side yield JFK’s death year, 1963. Also, 38th
prime number is 163 and 2 times 163 yields 326.
Coincidentally, 11221963 was the 326th day of 1963.
• Also, replacing digit 0 in RFK’s 38th birthday
(11201963) by digit 2 leads to JFK’s death day.
• RFK died on 6061968, 8 days after JFK’s 51st
birthday, 5291968. The prime factors of RFK’s death
year 1968 (2, 3, and 41) add up to 46, JFK’s death
age. The prime factors of RFK’s death day 606 are 2,
3 and 101 and 101 – (2 + 3) = 96, JFK’s age today.

RFK’s Birth Year Yields JFK’s Birth Date
• RFK’s birth year is 1925. The prime factors of
1925 are 5, 7, and 11. Interestingly enough, the
square of the sum of these primes yield 529, that
is, JFK’s birth date, May 29.
• Note that reverse of 529 equals the rightmost
three digits of 1925.

JFK is 96
• If JFK was alive today, he would have been 96 years
old. Twice 96 equals 32 x 6 where 32 and 6 put side
by side makes 326. JFK was killed 50 years ago, on
the 326th day of 1963, 11221963.
• The digits of JFK’s death date, 11221963, add up to
25, which coincidentally equals the sum of the
numbers assigned to the letters of JFK’s common
name, “Jack”. Also, the sum of the squares of the
digits of JFK’s death age, 46, equals 52, which is
reverse of 25.
