Are you like me and always wondering what prime factorisation the next calendar year will bring? LoL. Well look no further, here are the prime decompositions of the whole century for your nerdy convenience!
$2016$ is composed of all single digit primes, while I'm really looking forward to $2017$, prime!, we haven't had a prime year since $2011$. This century there are a total of $14$ prime calendar years and the decade of highest density of primes is $2080-2090$ within which there are four prime years. Fascinating isn't it! $\Large{ {o\;o\atop |} \atop\smile}$
