ἀνάρχη, in antiquity, a name given by the Athenians to four supernumerary days in their year, during which they had no magistrates. The Attic year was divided into ten parts, according to the number of tribes, to whom the precedence of the senate fell by turns. Each division consisted of 35 days; what remained after the expiration of these, to make the lunar year complete, which according to their computation consisted of 354 days, were employed in the creation of magistrates, and called ἀναρχικοί, and ἀναρχική.
