摘要： A perpetual calendar that simultaneously and individually displays all twelve months of any predetermined year. The perpetual calendar includes an outer housing sleeve having twelve month-windows, a middle panel movably disposed inside the sleeve, and a numerical calendar grid adorning the middle panel behind the month-windows. The preferred embodiment of the perpetual calendar also includes positioning structure for orienting the middle panel and therefore the calendar grid among fourteen possible yearly positions, as well as indicia for displaying the current yearly position in which the calendar is oriented. The calendar grid includes twelve month-grids that are each configured to display only a single particular month of the year and to display the precise number of days in that particular month. Each of the month-grids includes a common year grid movable among seven common year positions and an adjacent leap year grid movable among seven leap year positions. The positioning structure positions the middle panel in one of the fourteen yearly positions according to calculated yearly chronology, thereby resulting in the twelve month-grids being oriented in the month-windows in such a manner as to display the dates of any predetermined year.
摘要翻译：一个永久日历，可同时显示任何预定年份的十二个月。永久日历包括具有十二个月窗的外壳套，可移动地设置在套筒内的中间面板，以及装在月窗后面的中间面板的数字日历网格。永久日历的优选实施例还包括定位结构，用于定向中间面板，因此定位在十四个可能的年度位置中的日历网格，以及用于显示日历所针对的当前年度位置的标记。日历网格包括十二个月网格，每个网格都配置为仅显示一年中的特定月份，并显示该特定月份中的确切天数。每个月网都包括一个普通的年度网格，可以在七个普通年份之间移动，也可以在七个闰年之间移动相邻的闰年网格。定位结构根据计算的年度年龄将中间面板放置在十四个年度职位之一中，从而导致十二个月网格在月窗口中以显示任何预定年份的日期的方式。

摘要： A calendar having a plate-like support adapted to be mounted in an upright or flat position. The support has a number of first strips having spaced, vertically aligned numerals thereon which indicate certain days of a month. The support has mounting means for removably positioning the strips in generally upright positions so that, when the strips are properly arranged on the support, the numerals on the strips will be in the proper positions to indicate the days of a particular month. A group of second strips with the months of the year printed thereon are used one at a time to indicate a particular month. Mounting portions on the support removably positions each of the second strips on the support. In one embodiment of the calendar, the support has a recess for storing the second strips which are not being used. In the first embodiment, the mounting portions are pegs which extend laterally from the flat front face of the support and are received in holes in the first strips. In a second embodiment of the calendar, the mounting portions are tabs which are stamped from the support and project laterally from the front face thereof for insertion into holes into strips. Other embodiments of the calendar are also disclosed.
