How the winners are selected: A custom written computer program selects a random twelve digit number. It takes the 3rd,6th,9th and 12th digits and creates a four digit number. If this four digit number is within the 0001 - 3000 range,then the winning number is assigned to the next day of the month. If the number is not within the range, then another twelve digit random number is selected and the process continues until each day of the month has a valid winning number. Once all the numbers are selected by the computer for the month, the four digit random numbers are matched with the master listing containing the names of the calendar owners and sellers. The complete Winners list is then posted to the website and appears in the next issue of the Cactus.
