And I read the old spec. as if dates could be listed separated by 
commas, one date for each day.
The nice solution is a compressed date list (like compressed point
lists):

list of [date] | [Adate:Bdate]

Example:
;DT[1996-11-20][1996-12-31:1997-01-03][1997-01-05]
means: On each day of the following days the game has progressed:
1996-11-20,1996-12-31,1997-01-01,1997-01-02,1997-01-03,1997-01-05

whereas ;DT[1811-4]
should mean something like: game played in 1811-4 (not necessarily
each day of that month.
