Mitambariko inoverengwa ichibva paPrime Meridian iyo inopiwa nhamba 0^o. Nhamba yemitambariko yeTaranyika inokwira zvichienda kuMabvazuva - nhamba dzichipiwa vara (+), kudzamara dzasvika pa +180^o. Nhamba yeMitambariko inodzika zvichenda kuMadokero, nhamba dzichipiwa vara (-), kudzamara dzasvika pa -180^o. Izvi zvinoreva kuti mutambariko weTaranyika +20^o huri kuMabvazuva kwePrime Meridian; mutambariko weTaranyika -30^o huri kuMadokero kwePrime Meridian.
