Claim:
A timepiece, comprising: a dial with indications of seven days of a week inscribed on the dial; an aperture pierced through the dial and being sized to allow seven dates of a month from D day to D+7 day to appear adjacent the indications on the dial; and a mechanism driven by a movement for indicating the date and the day comprising: a date indicator bearing a series of dates from 1 to 31; a first member configured to cause the date indicator to move by seven days between the D+7 day of a first week and D day of the following week; a date corrector bearing a series of dates from 1 to 6 and arranged in such a way that the date corrector can be partially superposed on the date indicator; and a second member configured to cause the date corrector to move in such a way that, at the end of a month having less than 31 days, the date corrector automatically hides incorrect dates and replaces them with its own dates.
