document | List of 9+9 azimuths synchronized by two solstices into Lumbard rural Calendar (Lombardia-2c)

Within the mathematical build of the Lumbard Calendar are preserved older systems ever in use, synchronized together the main complex, like the 9+9 azimuths scheduled by two distant seasons apart, and exactly maintained between the two solstices, even using positions already measured by strings of 176 or 177+177=353 not 354 days. These distances are recurring at least five times around the year and so will not be fortuitous, but precise commands and measurements.
