Funny Programmer Halloween Design - Merry Christmas OCT 31

design on product

Why do programmers always confuse Halloween with Christmas? Because OCT 31 = DEC 25. A design for programmers inspired by this classic programmer dad joke.

Celebrate Halloween like a programmer and wish your friends and co-workers a Merry Christmas on October 31. Put a smile on their faces with this design on a shirt, sticker, mug or other product. You may need to explain how octal and decimal notations work.

This design consists of an orange pumpkin wearing a Christmas hat, the greeting “MERRY CHRISTMAS” in a curved horror style font and the text “OCT 31” on the sides. The whole design is enclosed by a shield like outline.
