Hillary Diane Rodham Clinton, born on October 26, 1947 in Chicago, Illinois, is an American politician and the Democratic Party nominee for President of the United States in the election coming up next month on November 8, 2016 [1].

Thirteen days before the US Presidential election, Clinton will turn 69 on October 26, 2016 this month and interestingly enough, her upcoming birthday possess some special numerical properties:

1. If Clinton’s 69th birthday expressed as 10/26/2016 or simply as 10262016 is split in the middle into 1026 and 2016, these two numbers are made of the same four single digits, namely 0, 1, 2, and 6, in different orders. Indeed, interchanging the places of digits 2 and 1 in 2016 results in Clinton’s birth date, 1026 (October 26). Note that Clinton’s 114th birthday written as 10262061 possess a similar property.

2. If numbers 1 to 26 are assigned to the letters of the English alphabet as A being 1, B being 2, C being 3, etc., the numbers assigned to the letters of Hillary Clinton add up to 172. Coincidentally, Clinton’s 69th birthday 10262016 equals 2 x 2 (9 times) x 3 x 3 x 17 x 131 where the sum of all the prime multipliers of 10262016 yields 172 too.

3. Furthermore, Clinton’s new age 69 equals 3 times 23 where the sum of these two prime numbers give 26, the day number of Clinton’s birth date. Additionally, half of the difference of 3 and 23 yield 10, the month number of her birth date.

4. Moreover, Clinton’s 69th birthday is to occur 13 days before the US Presidential election to take place on November 8. Interestingly enough, the sum of the squares of the digits of 13 result in 10, the month number of Clinton’s birth date, and the difference of the cubes of the digits of 13 yields 26, the day number of her birthday. Wow! Note also that twice 13 equals 26.

The above number connections related to Clinton’s upcoming 69th birthday are indeed special and for fun. However, for those superstitious people among us, could some of them pose other meanings?

Happy 69th birthday, Hillary Clinton!
