pass as native is the four-day market-week, with its development the 16-day period, and perhaps also the too little known 6-day week. In Java, Bali, and Sumatra there is a five-day market-week called _pasar_, in Bali also a four-day _tjaturwara_[1106]; alongside of these the seven-day week is in use. But wherever among heathen tribes a ‘week’ is spoken of, this is always the market-week[1107]. In Java and Bali the _pasar_-week is combined with the 7-day week in divisions of 35 days. Six of these periods form a _wuku_, a kind of year of 210 days. Besides these there are still other divisions, which are of importance for the sooth-sayers. The non-Islamite Lampong of Sumatra combine the _pasar_-week with the lunar month, which is counted as 30 days[1108]. We have here nothing to do with the highly developed time-reckoning of those peoples that drew up their systems under Indian and Islamite influence. This five-day week has a very extensive use in Further India: we meet it in Tonkin, in the Lao states of northern Siam, in Upper Burma among the Shan; further in Celebes and in certain parts of New Guinea. In the Malay Peninsula there is a five-day period for the determination of lucky and unlucky days. In other parts of New Guinea and in the Gazelle Peninsula of New Pommern the market takes place every third day. Of market-days in Polynesia there are unfortunately only uncertain accounts[1109]. In ancient Mexico a market was held every fifth day at every important place, just as in Africa on different days in neighbouring districts; the day was a rest-day, and with the market games and amusements were associated. This five-day market-week appears also in other parts of Central America. The Muysca of Bogota in Columbia, on the other hand, held markets every third, and the Inca peoples every tenth, day, when the country-folk ceased from labour, assembled in the towns, and engaged in traffic and games[1110]. These three- and ten-day periods are said to be brought into connexion with the month; if this statement be correct, they are not continuous periods, and the market-day must sometimes have been pushed out of place in order to secure the agreement with the moon; but the certainty cannot be ascertained. The market-week exists therefore, as we should expect, only among peoples with a more fully developed commerce and trade. The rule attains greater importance for the time-reckoning only when, as in the East Indies, it is introduced into an already existing calendarial system. In Africa larger divisions of time have arisen on the basis of it, and in one case, that of the Yoruba, the agricultural year has been thus divided. The market-weeks, however, may also occur independently, alongside of the calendar, like the Roman _nundinae_, which were held every eighth day and took their name (from _novem_) from the inclusive reckoning.
