2039

+ A full moon will occur on Halloween in 2039. Primal instincts will be at a maximum on this creepiest night of the century.

+ The largest gap between consecutive prime years this century occurs after 2039. (Add 2+0+3+9 to 2039 to find the next prime year.) [Honaker]

+ The sum of first 37 semiprimes. Note that 37 is also an emirp. [Bajpai]

(There is one curio for this number that has not yet been approved by an editor.)
