Why isn't Sonia Schmuschkowitz's Yahrzeit Exact?

We do not know the exact date of death of Sonia Schmuschkowitz. 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 Sonia Schmuschkowitz on 27 Shevat. If you know the exact date of death of Sonia Schmuschkowitz, contact us via the contact page.
