Naiparkuan Calendar

According to Coloria Planetary Physics, a lunar cycle (the time it takes for Coloria to orbit the Gas Giant completely) contains 32.6583 days, while a solar year (the time it takes for the Gas Giant to orbit the sun completely) contains 1964.3333 days. Thus, a solar year would contain 60 complete lunar cycles plus 4.8353 days.

Based on this information, Naiparkuan Calendar is a lunisolar calendar with 60 lunar months in a year (30 months with 32 days, 20 with 33 days and 10 with 34 days). This results in 1960 days in a lunar year (4.3333 days behind a solar year)

In a perfect scenario, where the difference between a lunar year and a solar year is always minimized, leap months would be inserted with the following scheme: This is more or less what is used in the Yanyuhoshe region. However, in most other regions, due to the Naiparkuan's preference for "easily manageable" numbers like 6 or 9, as well as the fact that seasons following the solar cycle is less important in the tropics, the leap months are inserted with the following scheme:
 * Every 8 years, one leap month of 34 days added (0.6664 days behind)
 * Every 8*50=400 years, one additional leap month of 33 days added (0.32 days behind)
 * Every 8*50*100=40000 years, one additional leap month of 32 days added (0 days ahead, but not implemented for now)


 * Every 9 years, one leap month of 32 days added (6.9997 days behind)
 * Every 9*6=54 years, one additional leap month of 32 days added (9.9982 days behind)
 * Every 9*6*9=486 years, 3 additional leap month of 32 days added; added in the 3rd, 6th and 9th 54-year cycle (6.0162 days ahead)
 * Every 9*6*9*6=2916 years, 1 leap month of 32 days not added (4.0972 days ahead, but not yet implemented)

In addition, after every lunar year, the lunar month cycles will have a delay of 0.502 days behind actual moon phase. To correct for this, 1 leap day is added every 120 months to the month of vyarvyet (another 1 leap day would need to be added every 60000 months, but it is not implemented since the establishment of Naiparkuan Calendar)
