How dates are decided

Intervals widen by steps

Repetition intervals move along a fixed ladder: same day, 1, 3, 7, 14, 30, 60, 120 and 240 days (on Standard).

Interval pace in settings swaps the days on those steps for Frequent (same day, 1, 2, 4, 7, 12, 20, 35 and 60 days) or Relaxed (same day, 1, 4, 10, 25, 60, 120, 240 and 480 days). The number of steps and how ratings move along them stay the same. A source can have its own pace too (“Interval pace” in its Library editor), and that wins over the setting. For a record on Frequent or Relaxed, “Why this date” says which pace placed it. If you applied “Intervals fitted to you” in CurveMora Plus, those adjustments scale the stage widths of whichever pace a record is on (see “Intervals fitted to you” in the Trajectory guide).

The rating you choose is what moves a record along it. Moving up, the next interval is the distance from the current step to the new one. Moving down, it is the gap between the new step and the one below it, counted from the day you rate it.

Once a record reaches the 240-day step, it comes back every 120 days.

Again returns the record to the 1-day step so you meet it again soon while keeping its existing history. The same rule applies after a long gap.

The reverse also applies. Recall something after a gap longer than it was scheduled for and it advances by however many steps that gap covered. After a 60-day gap, it moves to the step that interval supports before the rating's own step is applied on top.

The first date

The confidence you set when adding a record decides which step it starts on.

The first interval depends on your initial confidence. Lower confidence brings the first repetition sooner; higher confidence allows a longer interval.

What importance and focus items change

Importance is how sure you want to be of remembering. Dates are computed to hold roughly an 80% chance of recall at the lowest setting, up to 95% at Critical.

Setting importance to High or above pulls the interval back by one step. A focus item pulls back by one as well, and something that is both comes back two steps sooner.

So importance does more than win priority on a crowded day — it raises how often you meet the record at all. Marking everything Critical grows the daily load, so it pays to reserve it for what you truly cannot afford to lose.

How far a date can move

A computed date carries a little room on either side — 15% of the interval earlier (up to 3 days) and 8% later (up to 2 days).

Breaks are avoided and crowded days are spread within that room. Keeping redistribution inside the allowed window preserves the intended repetition interval while balancing daily load.

When a day would run past your daily target, the overdue records go down first, then the important ones, then the ones you have lapsed on most. Whatever still does not fit stays on the day, marked over capacity.

Overdue records are the exception. Their room lies entirely in the past, which offers no day you could actually use, so they are re-anchored on today with up to 14 days of room opened ahead. The most overdue take today first, and the rest spread to stay within your daily target.

Reading “Why this date”

After saving a repetition, or from a day's breakdown on the calendar, you can open the reasoning. Each rule that applied is listed, one line each.

How the next date is calculated

The next date is calculated from repetition history and settings using a fixed procedure. The same history and the same settings produce the same date whenever it is computed.
