Try to realize such calendar and computation of time... http://energodar.net/ha-tha.php?str=vedy/kalendar. Fully astronomical. Everything is linked to a geoposition. Year begins sunset in day of an autumn solstice. Year consists of nine months, three seasons, in a month 40-41 days, days-16 hours etc... Now on him there is the 7524th year. It is not a usual calendar, it is magic! It is the real explosion of a brain on the adult! Nobody could realize on mobile devices.
