Why isn't Hirsch Hirschmann's Yahrzeit Exact?

We do not know the exact date of death of Hirsch Hirschmann. 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 Hirsch Hirschmann on 13 Tammuz. If you know the exact date of death of Hirsch Hirschmann, contact us via the contact page.
