The * 19th Curse* will be cast October 31. This day is also commonly known as

As all computer literates know, "Curse 19" (Hex 19), Christmas (Dec 25) and Haloween (Oct 31) are computationally identical.

**Proof**

Christmas falls on Dec 25 each year. DEC 25 (or in expanded form Decimal 25) = 2x10 + 5 = 25 to normal people

The 19th Curse (or spell or Hex) falls on Hex 19. HEX 19 (or in expanded form Hexadecimal 19)] = 1x16 + 9 = 25 to normal people

*Notes:*

In Computer jargon: OCT = "Octal" or base 8; DEC = "Decimal" or base 10; HEX = "Hexadecimal" or base 16.

From the Calendar: October 31 = "Haloween"; December 25 = "Christmas".
