This article describes a type of anniversary reaction in which the patient has experienced a traumatic early loss and the duration of the therapy relationship functions as an anniversary trigger. Two cases are presented to illustrate how early losses may be repeated in psychotherapy, with the timing of repetition duplicating almost exactly the timing of the original event. Many writers have commented on the ubiquitous power of transference and on the patient's tendency to repeat past traumas; this article suggests that the timing of the original loss also may be brought into the transference.
