The Gainese Empire was once one of the most technologically advanced the world had seen and sprawled across the Tropical islands of the Carribean Ocean. It was these people who over 50,000 years ago developed a calender that is used by them. Since there Empire lied under the land that never sleeps, they could not tell when the sun fell. So they could only tell when the planet moved from sun to sun passing all Five Suns in the year. Unlike the Athenians who devised a 1095 day calender, the Gainese developed a much longer 10,000 day calender. As every 10,000 days there is a short 5 minute period where all of the southern side of the planet goes dark. The Northern part remains the only true side that never sees sunlight and remains dark. Never has it been recorded that light penetrated the sky.
It was said the Goddes Mayhem gave the ancient king Telapolo I a calender in his sleep. She said that it was to allow the people know when Misteif would cause earthquakes.
The Gainese Calendar starts at 1 G.C. which literally means the first year of the Gainese People. There is no B.G.C. in the Gainese Calendar. Currently the Gainese Calendar is at year 51345 G.C.
