...from the documents currently available it seems that the Chinese adhered not to a seven-day week [...] but to a lunar calendar, in which days were arranged in repeated sequences of sixty paired cyclical symbols, with the nearest equivalents to "weeks" being counted in blocks of ten days. Such ten-day blocks also dictated the rhythms of local markets in town and countryside.

I don't suggest that anything as revolutionary as giving up the week be considered (who would, since such a suggestion would be lunacy), but I don't see the harm in coming up with a name for 10 days, perhaps based on "deca-" or whatever the Old English or Middle English for "10" is.

Any suggestions?

Incidentally, it's been a little more than 10 days and a little less than a fortnight since I last posted, for which my apologies -- my work has been keeping me quite, well, busy.

P.S. Some other accounts (no link provided) are inaccurate and contain gross mistatements, which some might want to categorize as "lies".
