Why isn't Adolf Gersoni's Yahrzeit Exact?

We do not know the exact date of death of Adolf Gersoni. 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 Adolf Gersoni on 14 Shevat. If you know the exact date of death of Adolf Gersoni, contact us via the contact page.
