Why isn't Fanny Fresko's Yahrzeit Exact?

We do not know the exact date of death of Fanny Fresko. 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 Fanny Fresko on 19 Heshvan. If you know the exact date of death of Fanny Fresko, contact us via the contact page.
