THE 18TH DECEMBER IS THE KEY:

12+14+12= 38 (3+8=11)

12+14+20+12= 58 (5+8=13)

or

1+2+1+4+1+2= 11

1+2+1+4+2+1+2= 13

The 18th of December is the 353. Day in Leap Years.

3+5+3= 11

There are 13 days remaining until the end of the year.

13

And now:

1+2/1+4/1+2 = 3/5/3 = 353

Remember the 353rd day...

Watch out!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
