Device for calculating weekly deadlines, characterized by being constituted by two discs superimposed, rotating one above the other, related to a central axis, each disc being provided with an indicative circular scale, with the two scales facing each other at their edges, with a scale formed by three hundred sixty-five radial divisions, corresponding to the days that have a common year, equidistant from each other, grouped in the respective months, and the other scale being composed of fifty-two radial divisions, as many as the year's weeks, plus a space equivalent to one day on the other scale, so that, placing the second scale with week zero indicating the day in the first scale is taken as a starting point, you can immediately know the dates corresponding to a certain week next, which are the ones facing it on the other scale.
