Don't lose track of the days between now and your favorite holiday -- Halloween!

This internet-connected LED matrix display running CircuitPython will tell you how many days, hours, and minutes left until Halloween! Uses Adafruit IO time server to keep in sync. And, it runs on either the Matrix Portal or a Metro M4 Airlift with RGB Matrix Shield.

Custom bitmap images make it spooky and festive!

BUT THAT'S NOT ALL! You can adapt the code in this project to create a countdown display for ANY EVENT! Use any graphics and colors you like, too!
