Dilemma
Is regret rational?
If the past is fixed and unchangeable, what kind of mental act is regret? An error, a duty, a lesson, a perspective on a moment that is still in some sense present?
Context
Therapeutic culture is split on regret. Cognitive-behavioral traditions tend to treat persistent regret as a cognitive distortion to be challenged: the past is the past, dwelling is unproductive. Other therapeutic traditions treat regret as moral data that should be processed rather than dismissed. Religious traditions vary even more sharply — Calvinism, Catholicism, Buddhism, and Stoicism all have rich and incompatible accounts of what regret is and what to do with it. The dispute looks emotional or psychological but rests on an older question about what kind of thing the past is.
Why it matters
A school's view of time determines whether regret is even coherent — whether the past is a fixed reality you can have the wrong attitude about, a flowing structure that includes the present, a cycle one keeps returning to, or a name for a set of present memories with no past existing now to be regretted. The practical question of how to handle one's own regret is downstream of which of these the past is.
The coordinates that split the schools
The stances
The past is as real as the present; regret is a real attitude toward a real thing.
60 schoolsOn this view, the past hasn't gone anywhere — it sits permanently alongside the present in the block universe. The events you regret are still there, exactly as they were. Regret is, accordingly, a real attitude toward a real feature of the world. Whether to dwell in it or move past it is a practical question; whether it has a coherent object is settled.

The past is part of a cycle one keeps returning to; regret is one of the gates of the cycle.
26 schoolsOn cyclical views, the past is not a fixed thing behind you — it is part of the ongoing structure of return: karmic cycles, cosmic cycles, the cycle of seasons and generations. Regret, on these views, is less about an unchangeable past and more about an ongoing relationship with patterns that keep appearing in different guises.

Other branches exist; regret tracks roads not taken that are nonetheless real.
5 schoolsOn branching views, what you regret not doing is, in some sense, what you did do — in another branch. The regret tracks the difference between the branch you are in and the branches you might have been. Whether this makes regret weightier or lighter depends on whether one identifies with this branch only or with all of them.

The past is not a thing now; regret is the present holding what is no longer.
39 schoolsOn these views, time is not a container that holds the past; the past is what isn't here anymore. Regret is then an act of the present remembering — sometimes instructively, sometimes pathologically. It is not an attitude toward a real past, because there isn't a real past to be addressed; it is an attitude toward the present's memory of what once was.

From the One's vantage, regret is itself a conventional category.
3 schoolsOn non-dual views, the framing of regret presupposes a chooser distinct from the choice and from the outcome — distinctions that hold at the conventional level but dissolve at the deeper one. Regret remains real where the apparent self runs the apparent past; the metaphysical question of whether regret is rational in some final sense shifts to whether the categories that frame it pick out anything ultimate.
Schools the coordinates don't place
These schools don't satisfy any stance's coordinate pattern strongly enough to be assigned — either because they decline to commit on the question (Confucianism is famously silent on what comes after; Pyrrhonian and pragmatist traditions suspend judgment), or because their attribute signature crosses categories in a way the five buckets don't capture.
