## Abstract

The beginning of the calendar record inscribed on the Mamari tablet has been dated to the day of the summer solstice of December 20, 1680 A.D. The moon was not visible earlier at night. Because of a possible solar eclipse it was a perilous day, a precursor of the future misfortunes: the motion of Halley's Comet of 1682 A.D. and the rebellion of the western tribes. The new data about the watchings of the star Antares have been obtained, too.
