Notation for Relative Calendar Events

      A simple method is given for entering events which are
relative to another calendar date.

      Consider a computer calendar system where the user can enter a
list of calendar entries in a variety of formats, including:
1) Annual
2) Regular monthly (e.g., the first of every month)
3) Irregular monthly (e.g., the first Monday of every month)
4) Weekly, daily, or every N days
5) Irregular (e.g., the first Monday after the first Tuesday in
November)

      Current art provides for a notation for these event types
roughly of this form:
   YYYYMMDD(...)     hhmm  hhmm  description
where the "(...)" gives the details of the desired date and format
(weekly, irregular monthly, etc.).  Some examples of this format are:
19900101(14,24)      1200 1300  Bi-weekly luncheon
19900101(DOM,3,12)   1200 1300  Luncheon every month on the 3rd
19900101(DWY,5,L,12) 1200 1300  The last Friday of each month
19900101(DOW,3,1)    1200 1300  Lunch the Wednesday after New Year's

article.)

dates of interest for business or personal use. For example, "the
Wednesday of the last full week in August" or "the Friday before the
15th of July". The method of this disclosure provides a notation for
"relative" events, where the number of days before or after an
already set date is given to calculate t...
