Why isn't Aron Epstein's Yahrzeit Exact?

We do not know the exact date of death of Aron Epstein. 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 Aron Epstein on 25 Kislev. If you know the exact date of death of Aron Epstein, contact us via the contact page.
