ABSTRACT:
A perpetual calendar in kit form which includes a visual display board for accepting grid sheets having an array of spaces corresponding to the days in a month. The current month is designated on the board by a positioning peg. The days of the week are denoted on tabs which are slidably positionable on the board for monthly orientation with the grid sheet. A writing instrument is suspended from the board in overlying position with respect to the grid sheet and is placed under a selected weekday for aligning monthly dates occurring on that day. The writing instrument also includes an adjustably displaceable date index which can be keyed to any date on the grid sheet. In addition, the writing instrument is further removable for recording information on the grid sheet.
