Isn't it locale dependent? BTW. Didn't you mean QCalendarWidget and not QDateEdit? The latter is just a spinbox. If you want to change settings of the calendar widget it user, you can use QDateTimeEdit::calendarWidget() and change its firstDayOfWeek property.

Here is a simple hack to change first day of week in QDateEdit using class inherited from QItemDelegate :

QWidget *MyDateDelegate::createEditor ( QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index ) const
{
	if ( index.column() == 1 || index.column() == 6 )
	{
		QDateEdit *de = new QDateEdit ( parent );
		de->setCalendarPopup ( true );
		QCalendarWidget *cw = const_cast<QCalendarWidget*> ( de->calendarWidget() );
		cw->setFirstDayOfWeek ( Qt::Monday );
		return de;
	}
	return QItemDelegate::createEditor ( parent, option, index );
}

QWidget *MyDateDelegate::createEditor ( QWidget *parent, const QStyleOptionViewItem &option, const QModelIndex &index ) const
{
	if ( index.column() == 1 || index.column() == 6 )
	{
		QDateEdit *de = new QDateEdit ( parent );
		de->setCalendarPopup ( true );
		QCalendarWidget *cw = const_cast<QCalendarWidget*> ( de->calendarWidget() );
		cw->setFirstDayOfWeek ( Qt::Monday );
		return de;
	}
	return QItemDelegate::createEditor ( parent, option, index );
}

It is not an example of good practice to remove const, but it works.

You must change the index of collumn(s) where QDateEdit will appear.

You should also implement setEditorData, setModelData, updateEditorGeometry, etc. according to your vision.
