Yes, at first glance it seems a bit counterintuitive, but when I read the documentation "Intervals by Category" (saying that the default, WEEKDAY17W, means that Friday, Saturday, Sunday are counted as the same day) and also tested the example WEEKDAY35W mentioned there (where apparently Monday and Tuesday are counted as the same day and, separately, also Wednesday and Thursday), I realized that WEEKDAY12W in conjunction with increment 0 and the "e" modifier was exactly what the OP needed: Whenever the initial target date falls into {Saturday, Sunday, Monday}, INTNX returns the last subinterval of this three-day interval (treated "as the same day"), i.e., Monday. All other days of the week are left unchanged.
