public String readableDay(Date d) {

Datetime dt = DateTime.newInstance(d.year(), d.month(), d.day());
return dt.format(‘EEEE’);

}

CASE(MOD( Record_Date__c – DATE(1900, 1, 6), 7), 0, “Saturday”, 1, “Sunday”, 2, “Monday”, 3, “Tuesday”, 4, “Wednesday”, 5, “Thursday”, 6, “Friday”,”")

For example, the start of a week is Sunday in the United States locale, and Monday in European locales."

If you convert it to a DateTime then you could probably use DateTime.format to emit the day string. 2. You could also keep it as Date but subtract it from the beginning of the week (which presumably is a Sunday), like date myDate = date.today(); date weekStart = myDate.toStartofWeek(); integer dayOfWeek= weekStart.daysBetween(myDate); Then you could apply your if statement to get the corresponding string.
