Our current calendar year, 2020, may be computed with the
same "formula" by using any of the one-digit primes (2, 3, 5
and 7), one at a time, as shown:
2020 = {[(dddd-dd)*dd]/(d+d)+dd-d}/(d+d+d) =
{[(2222-22)*22]/(2+2)+22-2}/(2+2+2) =
{[(3333-33)*33]/(3+3)+33-3}/(3+3+3) =
{[(5555-55)*55]/(5+5)+55-5}/(5+5+5) =
{[(7777-77)*77]/(7+7)+77-7}/(7+7+7). [Rivera]
