val weekDays = resources.getStringArray(R.array.week_days_short).toList() as ArrayList

if (baseConfig.isSundayFirst) {
    dayBits.moveLastItemToFront()
    weekDays.moveLastItemToFront()
}

var days = ""
dayBits.forEachIndexed { index, bit ->
    if (bitMask and bit != 0) {
        days += "${weekDays[index]}, "
