Why isn't Selde Steinberg's Yahrzeit Exact?

We do not know the exact date of death of Selde Steinberg. 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 Selde Steinberg on 20 Heshvan. If you know the exact date of death of Selde Steinberg, contact us via the contact page.
