This program is Freeware, and the visual basic source code, ugly though it may be, is available for free as well. This application is not, in any form, to be sold or included in a collection for sale. In other words, I'm not using this to make money, and you can't either, but you can give it away, tweak it, etc. as long as you include my email address, web page, and name in your modified code and readme.txt. If you find and fix an error, I would appreciate an email describing where the error is and how you fixed it.

• Calculations take place automatically upon change of the date or the correlation.
• The year is limited to 9999 BCE to 9999 CE; if either of these values is exceeded, the year value will roll over to the other.
• The Up/Down buttons for the Day and Year are in the context of time, not number; i.e., pressing the up button on the Year when in CE will increment the year by one. Pressing the up button when in BCE will increment the year by -1.
• The Date-O-Matic will change the date by one day, repeatedly. Click ">>" to move forward in time, and "<<" to move backward. The rate of change is controlled by the slider labeled "Rate"
• Pressing the "Start Point", "Mid Point", or "End Point" buttons will set the date to the corresponding date in terms of the selected correlation.
• Since 13 Baktuns is commonly represented as 0 Baktuns at the start point of the correlation, a small zero will appear beneath the Baktun indicator when this is the case, and at the corresponding points in multiples of the cycle.
• To the right of the Date-O-Matic, a display indicates the day of the week and leap year status of the slected date, along with the Mayan and Julian day counts.
• To reveal the correlation constants used, select the correlation desired, then click "Start Point"; the correlation constant used will be displayed as the Julian day count.
