•Last year(2017) was prime itself   (i-e it′s once of a prime)  and present year is twice of a  prime:        2018=2×1009  and the next year is thrice of a  prime:        2019=3×673  • Sum of the digits of new year  is prime 2+0+1+8=11    Sum of the sum of digits=1+1=2  is also prime and the smallest  prime.
