nine times nine to dispel the cold (11. 252)

In northern parts of China, where the winter months can seem particularly long and bleak, a folk-reckoning of the time until spring’s arrival emerged in ancient times called “Counting the Nine” (shujiu, 數九) and is still observed. Beginning on the solstice, the season is divided into nine intervals of nine days each, this form of almanac or Advent calendar (the number nine chosen as a seasonally accurate number and concept of renewal or reset as it the last digit before leaping to a new exponent) was not only important to farmers and herders for anticipating the planting season and return of growth, they also were a welcome distraction (eighty-one days is a long time) that taught numeracy and literacy—families devising activity posters, like with plum blossoms, mnemonics or other early indicators in the environment, to countdown the days.
