Hi! If you look at the sources of DayOfWeekRow (here) , you'll see that there is no chance to get what you want. But you can build your own item in two minutes:

main.qml

import QtQuick 2.7
import QtQml 2.2
import QtQuick.Controls 2.1
import QtQuick.Layouts 1.1

ApplicationWindow {
    visible: true
    width: 640
    height: 480

    MyDayOfWeekRow {
        backgroundColor: "skyblue"
    }

}

MyDayOfWeekRow.qml

import QtQuick 2.7
import QtQml 2.2
import QtQuick.Controls 2.1
import QtQuick.Layouts 1.1

Item {
    implicitWidth: row.implicitWidth
    implicitHeight: row.implicitHeight

    property int format: Locale.ShortFormat
    property color backgroundColor: "orange"
    property color textColor: "black"
    property real rightPadding: 6
    property real topPadding: 6
    property real leftPadding: 6
    property real bottomPadding: 6
    property real spacing: 6

    // --- private ---

    id: control

    function getStandaloneDayName(d) {
        return Qt.locale().standaloneDayName(d, control.format) // use default locale
    }

    Component {
        id: itemDelegate
        Text {
            text: getStandaloneDayName(model.index)
            font.bold: true
            color: control.textColor
            horizontalAlignment: Text.AlignHCenter
            verticalAlignment: Text.AlignVCenter
        }
    }

    Rectangle {
        id: background
        anchors.fill: parent
        color: control.backgroundColor
    }

    Row {
        id: row
        rightPadding: control.rightPadding
        topPadding: control.topPadding
        leftPadding:  control.leftPadding
        bottomPadding: control.bottomPadding
        spacing: control.spacing
        Repeater {
            model: 7 // starts with Locale.Sunday = 0
            delegate: itemDelegate
        }
    }

}

@Wieland solved just adding

delegate: Text {
            text: {
                if (globalModel.isSundayFirst)
                    Qt.locale().dayName(model.day === 0 ? 6 : model.day - 1, Locale.ShortFormat)
                else {
                    Qt.locale().dayName(model.day, Locale.ShortFormat)
                }
            }

            horizontalAlignment: Text.AlignHCenter
            verticalAlignment: Text.AlignVCenter
        }

to default DayOfWeekRow like said here . But man, thank you so much for Qt.locale() function, i was struggling for hours figuring out why Qt.dayName() doesn't want to work. Nobel Prize for you brother.
