or fimmt, f. a number of five: fimtar-tala, u, f. a set of five or multiple of five (as fifteen, fifty, etc.), Bs. i. 190.

2. [Swed. femt = a kind of court], a law phrase, a summoning before a court with a notice of five days: a standing phrase in the Norse law, so that the verb fimta means to summon: so, fimtar-grið, n. pl. a truce during a fimt, N. G. L. i. 342, 351; fimmtar-nafn, n. a citation with a fimt’s notice, 86; fimmtar-stefna, u, f. a citation before a court with a fimt’s notice, K. Á. 184: the phrase gera e-m fimt simply means to summon, N. G. L. i. 346, passim; one fimt is the shortest notice for summoning, five fimts the longest,—fimm fimtum hit lengsta, ef hann veit nær þing skal vera, 21:—the law provides that no summoning shall take place on Tuesday, because in that case the court-day would fall on Sunday, the day of summoning not being counted, N. G. L., Jb., and K. Á. passim.—This law term is very curious, and seems to be a remnant of the old heathen division of time into fimts (pentads), each month consisting of six such weeks; the old heathen year would then have consisted of seventy-two fimts, a holy number, as composed of 2 × 36 and 6 × 12. With the introduction of the names of the planetary days (vide dagr) and the Christian week, the old fimt only remained in law and common sayings; thus in Hm. 73,—‘there are many turns of the weather in five days (viz. a fimt), but more in a month,’ which would be unintelligible unless we bear in mind that a fimt just answered to our week; or verse 50,—‘among bad friends love flames high for five days, but is slaked when the sixth comes;’ in a few cases, esp. in ecclesiastical law, sjaund (hebdomad) is substituted for the older fimt, N. G. L. passim; it is curious that in Icel. law (Grág.) the fimt scarcely occurs, as in Icel. the modern week seems to have superseded the old at an early time.
