2015 is mathematically sound.
20 is 4*5 and 15 is 3*5. 2015 is 5*13*31.
13 and 31 are reversed digit prime numbers.
In binary 2015 is 11111011111, a palindrome.
2015 is also 3737 in base 8 (octal) and 37 is the most special number of all in my opinion. For one thing, it’s the best age. For another, it’s the first irregular prime number !
