IThe cost factoris particularlyimportant when large Acalendarpads :are -desired. 'Ordinary calendar pads have to be printedseparatelyf'in sheets, then Acollated, glued, cut, Wand nally 'stitched to thefcalendar proper. The kmaking of; even small conventional f calendar date pads viis vthus very expensive'and orathis reasonl'flarge :pads are rarely Vusedj'for coeop'erative-calendars since their price isiprohibitive yand their useis usually confined -j to" small r run yissues of: special 1 calendars.

each side, alternate rowsl inverted. These Ycolumns are-soarrange register with Lthe date. number. apertures the card. Similarly be displayed through an aperture. In other words, the vertical spaces between the apertures will cover two columns while the apertures will display one column. The spaces extending horizontally between the date number apertures will conceal every other row of date numbers.

In Figure 1 there are seven columns of date apertures and it will be seen that by sliding the card 2 in its pocket horizontally of the cover l, various combinations of numbers will be obtained and displayed through the date apertures. The date numbers 2a run consecutively from 1 up to the total number of days for each month in the manner of an ordinary calendar starting on the desired day. but appearing only in every third column in view of the fact that the two intermediate columns are concealed by the cover member. In Figure 2 it will be observed that there are three series of date numbers commencing with 1 and these are used to portray the months of January. February and March. Similarly. with regard to the inverted numbers. there are three series which are used to portray the months of April, May and June and this can be done by removing the card from its pocket and inverting it and sliding it back into the pocket in inverted position as will be hereinafter more particularly described.

Arranged at the top of the columns of date numbers are a series of day indicia representing the days of the week. In Figure 1 the month of January 1948 is shown. This month begins v on a Thursday so that the day indicia for Thursday appears over the numeral l and indicia representing the other davs of the week in proper order commencing at Sunday therefore appear at the top of every column of date numbers.

Day indicia 2b also appear at the bottom of the columns. it being understood that the bottom of the columns will become the top of the columns when the card is reversed. In Figure 2 the date numbers for the months of January, February. and March are shown upright and the date numbers for the months of April. May and June. are shown inverted. In Figure 3 the date numbers for July, August and September are shown upright and the date numbers for the months of October, November and December are shown inverted.

The card is so constructed relative to the pocket in which it ts that when the card is inverted, the date numbers which were inverted then appear right side up and will show through the date number apertures ld and the date numbers which were upright will be inverted and concealed by the day indicia which were formerly inverted will appear to be upright and will be displayed through the day indicia apertures lf. whereas the inverted day indicia will be concealed by the card.

Month indicia are provided by means of month letters 2 which appear across the top and bottom l of the card in apparently jumbled arrangement arranged above and below and in alignment with the date number columns. However, referring to Figure 2 by way of example it will be observed that every third letter forms part of the usual abbreviation of a month designation. For instance the rst letter J, fourth letter A and the seventh letter N form the abbreviation for January; the second letter F, fth letter E and the eighth letter B form the abbreviation for February; and the third letter M and the sixth letter A and the ninth letter R form the abbreviation for March. These letters are adapted to register ber.

with the month indicia or month letter apertures le which are spaced apart similarly to the date number apertures Id so that the two intermediate letters are concealed revealing only every third letter to form the month indication for the various months portrayed by the particular side of the card.

It will be observed that by the arrangement above described, a single card having alternate rows of numbers inverted and printed on both sides will enable the user to portray in succession the twelve months of the year, by sliding the card in the pocket to display different months, removing it and inverting it, and reversing it.

In the modied form shown in Figures 5 and 6 a bilingual calendar is shown. This necessitates an extra column of date number apertures Id, or a total of eight as compared with a total of seven in the construction shown in Figure l. However, only seven columns of date numbers are used at one time, the same as in Figure 1. In the construction shown in Figure 5 preferably there is enough blank margin on the card to show behind the nal unused column at either side of the calendar.

In Figure 5 there are two rows of day indicia 2b, the day indicia in each row being vertically above or below, as the case may be, the day indicia in the other row and also arranged above and below and in line with the columns of date numbers.

The day indicia are in both French and English, the French indicia being sometimes in the upper row and sometimes in the lower row in each case. The day indicia apertures if are staggered, that is to say four of them are in line for registration with the upper row of day indicia and four are in line for registration with the lower row of day indicia.

The month letters 2c on the card are also ar, ranged in two rows and they are adapted to form the ordinary abbreviations for the months in both English and French. Figure 5 shows the month of January in French displayed. The month letter apertures le are vertically oiset or staggered, the central one being above the two others and registering with the upper row of month letters 2c, whereas the other two month letter apertures register with the letters in the lower row of month letters.

As in the case of the day indicia, the month letters in the upper row combine with the month letters in the lower row to make up combinations representing months in both English and French, and by moving the card shown in Figure 6 behind the cover, the months of January,-February and March in both English and French language will be shown, and by reversing the card the months for April, May and June in both English and French will be shown, individually. On the reverse side of the card, not shown, is a similar arrangement for the months of July, August and September, and October, November and Decem- Referring to the card shown in Figure 6, it will be noted that by using the upper row of month 1 letters 2c as the middle letter of the abbreviation for each month and two of the letters in the lower row, the following combinations may be made up starting from the left: J A N; F E B; M A R; J A N (French); F E V (French); M A R (French) and that when the French month abbreviations are shown the French day indicia will 4 be displayed through the day indicia apertures.

The additional column of date number apertures ld is required because of the fact that the sataeegeze :single:icardrequiressaigreaterznumber :,ofrfcombinaationszto: duplicate; the'three-'mori tris` int both-Eng- `lish andfFrench'. :It ysWill .bernote'd .that :thasame columns: ofifdatexnumbersfrserve .forsbothrFren'ch .1 :and L English iandethisis madenpossibie .byithemse fof? an additional .columniofaapertures.
