KALENDAR, is used for the catalogue or fasti anciently kept in each church, of the saints both universal and those particularly honoured in each church; with their bishops, martyrs, &c. Kalendars are not to be confounded with martyrologies; for each church had its peculiar kalendar, whereas the martyrologies regarded the whole church in general, containing the martyrs and confessors of all the churches. From all the several calendars were formed one martyrology: so that martyrologies are posterior to calendars.
