The day counter is a divide-by-7 counter that counts from 01 to 07 and up 07 before starting again from 01. Values that
correspond to the day of week are user defined but must be sequential (i.e., if 1 equals Sunday, then 2 equals Monday, and so on).
Illogical time and date entries result in undefined operation.
