ABSTRACT:
An elapsed time display and reminder device that is manually adjustable by the user to select a time in the future that may be many days in advance of the present, and to provide a calibrated countdown display of the progressively diminishing time interval until the selected future time is reached. In a preferred device, the user enters the present time and the future time in calendar form as a month and day of the month, and the device automatically converts this future calendar date less the present date, into an elapsed time interval as a number of days.
