Many of the days of the year are simply set down as 'favorable' or 'unfavorable,' while others were noted as days portending 'distress,' 'trouble,' 'tears,' 'injury,' 'everything favorable,' 'darkness,' 'moon obscured,' and the like. Of special interest are the prohibitions regarding food on certain days. On the 9th day of the 2d month "fish is not to be eaten or sickness will ensue." Swine's meat is forbidden on the 30th day of the 5th month, and in this case the particular kind of sickness--disease of the joints--is specified that will ensue in case of disobedience. On another day, the 25th of the 7th month, beef as well as pork is forbidden, while on the 10th day of the 8th month and the 27th day of the 6th month, dates are forbidden as a precaution against eye disease. One is not to cross a stream[622] on the 20th day of the 5th month; on certain days one is not to sell grain; other days are again noted as specially favorable for military movements. Some of the precautions prescribed in this calendar may have been meant for the populace in general, such as the order not to cross a stream or to strike a bargain. The belief in lucky and unlucky days has a distinct popular flavor, but it is doubtful whether the ordinary public consulted the priests, as a general thing, in order to find out what days were lucky and what not. It is more plausible to assume that the priests embodied in their official calendars some of the notions that arose among the people, and gave to them an official sanction.
