The new quarter starts today - 1 July
the 1st of July through the 30th of September.
You may wonder why we don't go from January to December.
Near the begining of the contest back in 1984 it was decided
to officially start each "year" on October 1st. This would allow for
the winners of that last quarter to be determined by the end of
the year. Remember, the 4th quarter deadline is 30 September and
then it takes time to process and judge all of the entries. Hence
the end of September "ending of the year". That applies to both
the writer and illustrator contests.
