Date-to-Set Workbench
Turn month, day, and year into a transparent candidate stream with visible keep, reject, duplicate, and extra decisions.
Method and limits
Candidate order is month, day, two-digit year, full-year digit sum, full-date digit sum, |month − day|, and |day − two-digit year|. This exact transformation is defined by NumberCalendar for transparent recreation. A date-based selection method changes how numbers are chosen; it does not change draw probability.
