Exactly when these peoples arrived in America and where they came from no evidence exists to indicate. Their base-20 number system, however, shows that they originally came from the old world of the eastern hemisphere. Their old 260-day calendar, whose shortness - 105 days shorter! - scientists and researchers have as yet been unable to explain, was, I believe, created in a country where the full solar year was indeed only 260 days long, as one of these days lasted 53 days and nights, and one of the nights was of similar duration: 53 + 53 = 106; 106 + 259 = 365. Such regions exist at latitude 700 N., i.e. the northernmost part of Alaska, very close to the Bering Strait, the northern shores of Canada, the middle of Baffin Island and Greenland, the northern part of the Scandinavian peninsula, and the land just south of Siberia's northern coastline. The ancestors of the Americans, gradually crossing over into America from Asia or Europe through Alaska or Scandinavia and Greenland, must have occupied these regions for a certain period of time together with the Eskimoes and the Lapps, and, indeed, appear to be offshoots of these races as they too are Mongolian. There it was, then, that they drew up the 260-day calendar, which was a full solar one, and from there during the course of the centuries they gradually spread throughout America where, of course, they came to draw up their new, regular 365-day calendar. Their old 260-day calendar, however, though obsolete, was retained for religious and ceremonial purposes, as their cycle of feasts was based upon it. A similar situation exists today: although we have the new Gregorian calendar, all the feasts within a period of 127 days - from the beginning of Triodion (the three-week period before Lent) until the Feast of All Saints – known as the feasts of Easter, or the feasts of Triodion and Pentecost, continue to be celebrated according to the old Julian calendar - by people who in all other respects follow the new calendar.
