how set week start day or First day of the week ?


How I change "First day of the week" for sun in Regional settings PT ?

If I change to Regional settings US the "First day of the week" is
Sunday when set pt_PT the "First day of the week" is Monday , I'd like
see my calendar beginning on Sunday , without break all regional
settings , How I do that in KDE plasma 5 Fedora 28 ?

in an old thread [1] or in kde 4 looks like this [2]
