Definitions

• the present invention is a perpetual calendar device making it possible to carry out the global and immediate transformation of the reading of the complete calendar of any year, regardless of that of another or all in other years, present, past or future, in Julien or Gregorian fashion, by restoring the name it bears to each day.
• the device of the invention is unique in that it uses a principle of global identification of each year which allows, thanks to a double coding, to establish its direct connection, without calculation or intermediate operation, with the together of the days which constitute it. It thus makes it possible to establish the detail of the fixed days and festivals which make up any year and to carry out the complete reading, in their natural order or in an indifferent order. It also gives, by memorizing several codes, the possibility of carrying out the simultaneous reading of several different years.
• the seven names of the days of the week being perpetuated according to the arithmetic base "7”, the elements of this base have been codified in order to be able to identify and to match the years with the names of the days which compose them. It follows that each year of the two calendars Julien and Gregorian is divided into two periods, each coded to correspond to one of the seven codes used to identify the days of a week.
• the system comprises two tables, both containing the codifications which reciprocally relate any year to its detailed calendar.
• the first contains the codification of the years
• the second contains the codification of the days.
• the codes of one correspond with those of the other in such a way that on the one hand, and among other examples (plates (1) and (3)), in the Gregorian period, the code (P1) assigned to Monday January 1 corresponds to the code for the first part of the year 1900; that the one (P2) assigned to Tuesday, January 1 corresponds to the code of the first part of the year 1901; that the one (P3) assigned to Wednesday, January 1 corresponds to the code for the first part of the year 1902; that the one (P4) assigned to Thursday January 1 corresponds to the code for the first part of the year 1903; that the one (P5) assigned to Friday January 1 corresponds to the code for the first part of the year 1904; that the one (P6) assigned to Saturday January 1 corresponds to the code for the first part of the year 1910; that the one (P7) assigned to Sunday January 1
• the first table (figure (1), plate 1) contains the codifications of all the years in the Julien calendar of the year 1 to year 1582 (T0), year of calendar change, and all years of the Gregorian calendar from year 1582 to a virtually unlimited age (until the future calendar revision). It is composed of twelve separate grids (A, B, C, D, E, F, G, H, I, J, K, L) each comprising one hundred double boxes respectively representative of each of the years of a century.
• the first seven grids represent the centuries of the Julien calendar, the last four (I, J, K, L), those of the years of the Gregorian calendar, the intermediate grid, that of the 16th century (H), is composite and includes the transition period between the two calendars.
• the grids of the Julien calendar (A, B, C, D, E, F, G) reproduce identically twice in the same order.
• the grids representative of the seven centuries from 100 to 700 (A to G) have codifications respectively identical to those of the period of the seven centuries 800 to 1400 (A to G).
• Each grid has a double coordinate system making it possible to read, century by century, five horizontal bands containing twenty years each (figures (1) or (2)).
• the year sought (1677) is represented by a couple of boxes, the one on the left corresponds to the period from January 1 to February 28 (P5), the one on the right to the period from March 1 to December 31 (P4).
• the representation of this year 1582 includes three boxes corresponding to three periods: (P1), (P7), (P4).
• the first (P1) corresponds to the current period from January 1 to February 28; the second (P7), from March 1 to October 4; the third (P4), from October 15 to December 31.
• the second table (figure (3) plate 3) is the complete codified calendar for a "typical" leap year of 366 days with, calendar by calendar, all twelve months of the year ( Figure (3) shows a partial view of this set).
• Each date (U) includes, next to itself, the list, abbreviated or not, of the names of the seven days of the week in their traditional order and, in addition to this, a series of each of the seven distinctive, graphic codes or colored, identical to those used in the first table to codify all the periods of the years in the Julien and Gregorian calendars.
• Each of the names in this list (Lu, Ma, Me, Je, Ve, Sa, Di) is itself matched, opposite or superimposed, with one of the seven distinctive codes (P1, P2, P3, P4, P5, P6, P7) initially placed in the order required to correspond correctly with those of the first table (figure (1)), so that when two dates follow one another, all of the seven distinctive codes of the second, arranged in the same initial order, shifts one day in the positive direction of time, compared to all seven names of days remained fixed (V3, V4).
• P1, P2, P3, P4, P5, P6, P7 initially placed in the order required to correspond correctly with those of the first table (figure (1)), so that when two dates follow one another, all of the seven distinctive codes of the second, arranged in the same initial order, shifts one day in the positive direction of time, compared to all seven names of days remained fixed (V3, V4).
• Figure (3) shows in fixed part, the names of the days of the week (Mon, Tue,
• the reading in order, day after day, of a normal year is carried out by considering in the first period, until February 28, the names affected by the first code found in the first table, then, passing the day of February 29 which only exists in leap years, to continue from March 1, in the second period, with the names assigned to the second code of the year.
• the two periods of the year are adjacent and combined into one. They are therefore assigned the same representative symbol throughout the year.
• the identification in the second table of the codification of a calendar affected by a determined name makes it possible to find in the first table, by identification of the same codification in the corresponding period, all of the years containing a day of same characteristics - it will thus be possible to determine all the years whose Christmas day falls on a Monday ((P6), figure (3)).
• the first table can show each centenary period presenting in isolation its own system of coordinates, showing the decades on the ordinate and the years on the abscissa (figure (5), plate 5: (A), (B ), (C), (D), (E), (F), (G), (H), (I), (J), (K), (L)); in another form of presentation (figure (6), plate 6), the set of the two Julien and Gregorian calendars in the first table is presented with the same coordinate system as above and arranged in a compact form: (A), ( B), (C), (D), (E), (F), (G), (H), (I), (J), (K), (L), which allows it to present a character universal: each country having its own calendar change year (TO), (T2), (T3), etc., the transition years are placed in the margin of the central table with the year preceding it in the Julien calendar on the left and on the right the following year in the Gregorian calendar; the
• the first table may present only partially, one or the other of the two calendars Julien and Gregorian; its coordinate system can be inverted and present the years on the ordinate and the decades on the abscissa; the two tables can be combined into a single assembly which can be positioned on any horizontal or vertical support and allowing their global viewing;
• the list of the seven days of the week in the second table (figure (7), plate 7), each day being respectively assigned its initial coding, can be presented with regard to the sequence of dates, in an order different from the order traditional and to correspond to the first day of the base year, a distribution not necessarily starting with a "Monday";
• the second table can be split so as to be able to present, one by one, or in groups, the twelve months of the year on different tables; in this case the calendar can be made up of a "notebook" of tables (figure (8), plate 7) formed of a shutter internally containing the first table foldable perpendicularly on a notebook of shutters containing the second
• each of the seven codes (P1, P2, P3, P4, P5, P6, P7) arranged in a horizontal continuous band, is assigned to each calendar day of the standard year of 366 days, from January 1 to December 31 .
• the seven bands of codes, each superimposed on all the calendar of the year, are placed one below the other, in the required order, by shifting one day at each overlay (X).
• the names of the days of the week are placed in a continuous strip in the traditional order (Lu, Ma, Me, Je, Ve, Sa, Su).
• the first calendar of the first coded strip (January 1) is mapped to Monday, the second to Tuesday and so on, throughout the typical year (W).
• the continuous set formed by the highest of the seven bands is divided into sequences of seven days, corresponding to pseudo-weeks.
• the set given the offset of the seven bands and the total number of days in the year, therefore comprises 54 sequences of seven days. Reading is carried out as above, first by identifying in the first table, tracking codes for a chosen year, then, by reading in the second table, the bands corresponding to one, then to the other. symbol.
• the detail of the days of the year is established by simultaneously reading the dates contained on these bands in correspondence with that of the continuous list of names of days (Z).
• the first seven bands of repetitive codes ((V1), (V2), (V3), (V4 ), (V5), (V6), (V7)) are each placed before all the dates assigned the same codifications.
• the dates are grouped by month, identified by different funds. All the months can be split on a table or arranged on the same horizontal strip and folded in accordion to constitute a pocket calendar (figure (12), plate 9).
• the invention in addition to calendars, almanacs or ephemeris makes it possible to create perpetual daily agendas that can be consulted in real time, continuously or sequentially, in chronological order or in any order for an indefinite number of 'years.
• These may contain, page by page, relating to each date, pre-existing information concerning events of a historical nature or be made up only of blank media which may be informed in the future by personal information, collected daily day after day, over several years, like a newspaper.
• the duration of use of the calendar is not limited in time except for the relationship between the allocated space and the amount of information to be included.
• the invention which makes it possible, at any level whatsoever in the Gregorian mode to carry out the reading of the days of a year in the Julien mode, can moreover, by simultaneous reading of their respective codes, in the two tables, serve to quickly establish the conversion of all the dates of an era that has remained in the Julian calendar (for example the Orthodox calendar), in that of the Gregorian calendar and vice versa.
