This is a simple desktop calendar, it shows all the dates in a given year set out in days and months. Christmas and Easter are highlighted.
You can move to the year of interest by clicking on the arrow buttons, alternatively click in the year icon, type in the year and press return to go to it. Clicking with the right mouse button on an arrow makes the date change in the opposite direction to clicking with the left button.
It is possible to save the calendar either as a text or a graphics file which can be imported into other programs like word processors.
The text version can be neatly formatted in your word processor by using a ruler with some right justified tabs.
Graphics files are saved with the same layout as the screen display e.g. four months by three months. You can change the displayed layout by dragging the bottom corner of the window to make it narrower or wider.
The standard Windows save window offers graphics formats of Windows metafile (.wmf), Windows placeable metafile (.wmf), and Windows enhanced metafile (.emf). The best one to use is .emf, if your software does not support that try the placeable metafile and failing that the ordinary metafile.
Placeable (and enhanced) metafiles include information about the size of the graphics contained which improves the chances of other programs being able to render them correctly.
The program can be given a command line parameter of the year to open at, otherwise it defaults to the current year.
The adoption of the Gregorian calendar by Britain (and its colonies) is followed, which makes September 1752 interesting to observe.
