A calendar having double length leaves is disclosed. Each double length leaf displays the second of two consecutive months (or other units of calendar time). The month takes up only half of the double length leaf or, in other words, the month occupies a space approximately defined by a single length of any given double length leaf. Each of the double length leaves functions, as a result, to refold and/or reposition in order to display its second of two consecutive months as the first of the next pair of consecutive months with any and all original scheduling notations preserved. Chronologic order of the two consecutive months visible is displayed from top to bottom. The double length leaf may, at the outset, be displayed full length and then be folded in half and up into its second position, or the double length leaf may begin in a folded-double position and be pulled up to its full length thereafter. The double length leaves are always folded along their widths at a line defined, approximately, by half the double length.
