Some fields are missing. Especially format option. It raises some bugs for localized versions of apps.

For example you can compare Norway version:

    days: ['søndag', 'mandag', 'tirsdag', 'onsdag', 'torsdag', 'fredag', 'lørdag'],
    daysShort: ['søn', 'man', 'tir', 'ons', 'tor', 'fre', 'lør'],
    daysMin: ['sø', 'ma', 'ti', 'on', 'to', 'fr', 'lø'],
    months: ['januar', 'februar', 'mars', 'april', 'mai', 'juni', 'juli', 'august', 'september', 'oktober', 'november', 'desember'],
    monthsShort: ['jan', 'feb', 'mar', 'apr', 'mai', 'jun', 'jul', 'aug', 'sep', 'okt', 'nov', 'des'],
    today: 'i dag',
    monthsTitle: 'Måneder',
    clear: 'Nullstill',
    weekStart: 1,
    format: 'dd.mm.yyyy'

Probably this one is correct:

monthsTitle: 'Meseci',
clear: 'Ponastavi',
weekStart: 1,
format: 'd. m. yyyy'
