Why isn't Zinovy Krawzow's Yahrzeit Exact?

We do not know the exact date of death of Zinovy Krawzow. 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 Zinovy Krawzow on 23 Kislev. If you know the exact date of death of Zinovy Krawzow, contact us via the contact page.
