Abstract
An electronic date calculator includes an electronic processor, input keys operably connected to the processor, at least one date function key corresponding with a selected date unit and operably connected to the processor, and a display operably connected to the processor. The processor is programmed to drive the display to show a present date. In response solely to entry of a multiplier from the input keys and a date unit from the date function key, the processor adds a product of the selected date unit and the multiplier to the present date to generate a resulting date, and drives the first display to show the resulting date.
Claims20
A date calculator, comprising:
- an electronic processor;
- input keys operably connected to the processor;
- at least one date function key corresponding with a selected date unit and operably connected to the processor;
- and
- a first display operably connected to the processor;
- wherein the processor is programmed to:
- (a) drive the first display to show a present date, and in response solely to entry of a multiplier from the input keys and a date unit from the date function key:
- (b) multiply the selected date unit by the multiplier, and add the product thereof to the present date to generate a resulting date;
- and
- (c) drive the first display to show the resulting date.
A method of calculating a date, comprising:
- Using an electronic processor, determining a present date and showing the present date on a display;
- inputting a multiplier to the processor;
- using a single key operably connected to the processor, inputting a date unit to the processor;
- in response to the input of the date unit, using the processor to add the product of the multiplier and the interval to the present date, so as to obtain a resulting date;
- and
- showing the resulting date on the display.
A computer program product comprising a computer-readable medium containing instructions causing a computer to carry out a method of calculating a date, the method comprising:
- determining a present date and showing the present date on a display operably connected to the computer;
- receiving an input of a multiplier;
- showing on the display at least one date function key, the date function key bearing indicia representing a preselected date unit;
- in response to the input of the date unit by the at least one date function key, adding the product of the multiplier and the interval to the present date, so as to obtain a resulting date;
- and
- showing the resulting date on the display.
