Henry,
See this link: http://www.crfg.org/pubs/ff/jujube.html
Note hardiness given there as 'about -28F'.
Note also very heat and drought tolerant.

At end of link above, is link to Lee Reich's book chapter on jujube; lots
on info therein, and for a number of other fruits grown by NAFEXers. This
book highly recommended.

As for where it grows in central Asia, there is disagreement on the origin
of the plant, whether in Syria, N. Africa, or also in central Asia.
Regardless, was valued in China thousands of years ago, and is very widely
grown there now, with around 400 cultivars. As I noted before, this fruit
is well known to all Chinese students and faculty I've worked with, as well
as Koreans.

I recall some articles posted here, about university trials of some unusual
fruits in the Canadian prairies and upper midwest. There may be data there
on jujube trials. Though keep in mind there may be a range of winter cold
tolerance within the hundreds of cultivars. (This is true for kaki/Asian
persimmons.) Also, note in the link above season of jujube ripening. I
would choose at least some early ripening cultivars, if you get freezes in
Sept. Fruit at our place usually ripens Sept into Oct.
