Abstract: A combination desktop calendar and picture frame which allows a user to insert his or her picture or photo of choice into the front cover of the calendar. A plurality of calendar pages are held inside the front cover. The calendar pages are somewhat wider than the front cover so that a portion of the calendar page is visible to one side of the front cover. The visible portion has a compact calendar printed on it which can be highlighted by marking important dates or by placing self stick clear or transparent, tinted shapes over important dates, each shape corresponding to a different type of event such as birthdays, anniversaries or the like. The internal construction of the calendar is such that the calendar pages may be flipped so that the current month or week is at the front most location after opening the front cover. An easel or magnetic backing is included for holding the unit in a substantially upright position on a desktop or countertop or attached to a refrigerator, file cabinet, wall, etc.
