Currently the Uzbek Wikipedia special pages are displaying dates without hyphen (as in 22 mart), but according to new rules (http://el.tfi.uz/pdf/lyoaoai_uzl.pdf) for latin based Uzbek script dates (and any ordinal number) should be written with hyphen (as in 22-mart). TL;DR: dd mm is wrong, dd-mm is right. Fully it would appear as dd-mm yyyy.
And the decimal separators. Currently they are displayed as xxx,xxx.xx, and should be as xxx xxx,xx (space instead of commas for 3-digit grouping, decimal comma instead of decimal point).
