Why isn't Jascha Zmodze's Yahrzeit Exact?

We do not know the exact date of death of Jascha Zmodze. 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 Jascha Zmodze on 25 Elul. If you know the exact date of death of Jascha Zmodze, contact us via the contact page.
