i typically use day of year only, its super helpful, especially when calculating time between dates, or time until date. Also i use metric time which makes life even easier for to the second calcs. For many people, myself included, regular breaks through things like weekends do not truly exist so there is no point tracking them in the main date format. You might need it on occasion but it is information so rarely useful that recording it every time i write or use a date is wasted energy, especially when you consider how frequently you need to handle long range dates which DOY does more direct than day of week / week of year.
