The Gregorian system in a new conception and layout, as a new style which combines solar and lunar cycles. The gregorian year is structured in 12 "holy nights" (the time between the 25 of December and 6 of January) and 12 real lunar month (synodic). This new calendar recombine loyalty to seasons with genuine lunar months, soothes the blurring of all other systems by the month "hug" of the 12 nights rounding. See ☀
