- As of yet Unknown.
As of yet, no known Date-a-mancer has been introduced.
As this magic is aligned with Numbers and with Hippiemancy, "date" may have a meaning similar to a calendrical date, making date-a-mancy an analog of numerology or astrology in some form or fashion.
However, it may also refer to "date" in the sense of a romantic pairing, i.e. "going on a date", and therefore be involved with love spells. This would be consistant with Hippiemancy ("Free Love").
