Ted's Computer World - A 10,000 Year Calendar

An Anytime Calendar

This utility comes in handy for keeping track of bridge dates, or any other date since year 1 a.d. Advantages over the utility built into Windows are that it understands that time began prior to 1980, and a full-year screen is available with a single mouse click.

There are two versions of the program:

CAL-12 features a full 12-month display on an oversized console screen. Requires Windows 2000 or greater, and a 1024×768 or greater screen resolution.

CAL-6 displays a pair of 6-month screens for each year, and will run on any Windows system. Use this program only if for some reason the 12-month version will not display properly on your computer.

*Download:*	CAL-12.EXE	For Windows 2000 or greater

*Download:*	CAL-6.EXE	For Windows 95 or greater

To preview a program online, click on its name, click /Run /Run.

IMPORTANT SETUP OPTIONS

CAL-12 utilizes a console windows that is not of standard size. It might not display properly on your monitor without some simple adjustment, as follows:

Create a desktop shortcut for CAL-12.EXE. Double-click the icon to launch the program. Right-click the colored bar at the top of the program window. Select Properties from the menu.
Under the Fonts tab, select 10×20 Raster Fonts.
Under the Layouts tab, set both the Screen Buffer Size and Window Size to Width=93 and Height=34. Click OK to exit the dialogue window.
Left-click the window bar and hold the mouse button down. Drag the window to the center of your screen, making sure that the entire window is visible.
Right-click the window bar again. Select Properties / Layout. Uncheck the box labeled Let system position window. Click OK.

The program screen should now be displayed in the same position every time you launch the application.

The CAL-6 program runs as-is in a standard 80×25 console window. You might like to make adjustments to font selection and screen placement, as above.

Usage: When in the program, type "Y", then "H" for a repeat of the instructions on setting up an efficient and more attractive interface. To exit the program, simply press <Esc>.

ABOUT THE DATES

The modern Gregorian Calendar was first instituted in 1582, in Italy by Pope Gregory. At that time, the days of October 5-14 were deleted in order to correct the error accumulated under the Julian Calendar. Modern computer systems, however, support the better-late-than-never British conversion date, wherein the days of September 3-13, 1752, were expunged. My programs conform to this standard.

No attempt is made to accommodate the old-style Julian Calendar. Other than the missing days, however, the only difference in the Gregorian Calendar is that years evenly divisible by 100, but not evenly divisible by 400, are not leap years (so far, the only such dates are 1700, 1800 and 1900, but 1700 is ignored by the British protocol).

In any case, all calculations are variable by location and nationality, as there was no worldwide standard until the 1920's or so. In fact, several different calendars remain in use to this day, with discrepancies of up to eight years!
