My parents are both mail carriers and their schedules are somewhat confusing. They always have Sundays off, but it could vary in which weekdays they have off. So for example say my mom has Monday off one week, then the next week she will have Tuesday off, then so on and so forth . However, say it’s the week she has Friday off, then she has that Saturday off as well. Then that week following a weekend she works six days a week. Here is how it looks like. X’s are the days they work

repeat back to having monday off. However sometimes they may get called in on their “off” day to work.
It varies with hours as well. My parents usually work 7:30–5. It really depends on if they have to work overtime or not. So it honestly just varies on many different things.
