Fairy Calendar

The Fairy Calendar (also referred to as the Metal & Gem Calendar) is the calendar system that is officially used in The Three Kingdoms and unofficially used in many other Good kingdoms.
The calendar divides the year into three equally sized months (Gold, Silver, and Bronze) each containing nine days (Ruby, Topaz, Emerald, Sapphire, Amethyst, Rose Quartz, Diamond, Opal, and Moonstone).
