Da su Zemljine vremenske zone međusobno razdvojene jedan sat, tada bismo imali 24-kratne zone, što zvuči prilično jednosatavno i logično.
Međutim, situacija je malo složenija od te. Budući da se mnoge vremenske zone razlikuju samo 30 ili 45 minuta, one se ne uklapaju u urednost i raspoređenost 24 sata, što znači da ih ima više od 24, mada je teško tačno reći koliko.
