Why isn't Mirjam Schapiro's Yahrzeit Exact?

We do not know the exact date of death of Mirjam Schapiro. According to Jewish tradition, if the exact date of death is not known, the yahrzeit of a person can be observed on any day, as long as it is that same day every year. Since that is the case, we observe the yahrzeit of Mirjam Schapiro on 19 Adar. If you know the exact date of death of Mirjam Schapiro, contact us via the contact page.
