[sq] Conditional Quarter Token
Prefix any of the quarter tokens with the letter "s" (s for start), to have these tokens appear only for dates in the first quarter of the year.
On other days the token converts to a blank. This is not a zap token. Blank means no text.
•In February: [sq] = 1, [s.q] = st, [s!qq] = first.
•In May: [sq], [s.q], [s!qq] are all blank.
