(For read/write) Day-of-the-week counter
*
1) The “

” mark indicates data which are set to 0 for read cycle and not set for write cycle.
*
2) Day-of-the-week digits are incremented by 1 when carried to 1-day digits.
*
3) Day-of-the-week digits display (incremented in septimal notation):

2) The automatic calendar function provides the following calendar digit displays in BCD code.
Day digits
:
Range from 1 to 31 (for January, March, May, July, August, October, and December).
Range from 1 to 30 (for April, June, September, and November).
Range from 1 to 29 (for February in leap years).
Range from 1 to 28 (for February in ordinary years).
Carried to month digits when cycled to 1.
Month digits :
Range from 1 to 12 and carried to year digits when cycled to 1.
Year digits :
*
3) Any registered imaginary time should be replaced with actual time as carrying to such registered imaginary time digits from lower-order ones cause
the clock counter to malfunction.
Range from 00 to 99 and counted as 00, 04, 08, ..., 92, and 96 in leap years.
