Why isn't Minna Kalmann's Yahrzeit Exact?

We do not know the exact date of death of Minna Kalmann. 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 Minna Kalmann on 17 Shevat. If you know the exact date of death of Minna Kalmann, contact us via the contact page.
