Why isn't Leib Grossmann's Yahrzeit Exact?

We do not know the exact date of death of Leib Grossmann. 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 Leib Grossmann on 13 Heshvan. If you know the exact date of death of Leib Grossmann, contact us via the contact page.
