zero – Start list (etc.) numbering at zero

The pack­age ini­tialises all ex­ist­ing coun­ters such that num­ber­ing, where ap­pro­pri­ate, starts at zero (in­stead of one). Num­ber­ing still starts at one for foot­notes on the ti­tle page, parts, foot­notes in mini­pages, and enu­mer­ated lists nested two lev­els or deeper, since these use a non-ara­bic num­ber­ing for­mat.
