The Year of the Pig is the final sign of Chinese Astrology, before the cycle repeats it self. In the West and America the Greco-Roman Zodiac plays a dominant role in newspapers and enthusiasts of things groovy and cosmic, but in the East another Zodiac from China fills the same void. Like the traditional Western Zodiac the Eastern Zodiac is divided into twelve teams that repeat themselves every twelve years instead of every twelve months.
The East has already made up symbols to represent Leo, Gemini, Virgo, Cancer, etc...so it's only natural that Western Symbols come to be to represent those signs from the East. In this case a stylized letter 'P' represents the Year of the Pig. The important part is the curly tip at the bottom that represents a pig tail. Likewise the colour for the Year of the Pigs background is pink.
The Year of the Pig is six years a way from now, so we will have to wait until 2019 to see how things shape up. Next up is the natural starting point for the Eastern Zodiac on one of the resourceful, clever, intelligent and maligned inhabitants of the Earth - the rat.
Just as the year in between the Dragon and Tiger has two forms as the Year of the Cat or Rabbit, so to does the Year of the Pig. In following the level up rule, the 'magical power up' form for the Pig is the Elephant. In parts of Thailand they call this they year of the Elephant instead of the Year of the Pig.
