Why isn't Rosa Finkelstein's Yahrzeit Exact?

We do not know the exact date of death of Rosa Finkelstein. 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 Rosa Finkelstein on 20 Shevat. If you know the exact date of death of Rosa Finkelstein, contact us via the contact page.
