Why isn't Schlaume Immermann's Yahrzeit Exact?

We do not know the exact date of death of Schlaume Immermann. 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 Schlaume Immermann on 23 Nisan. If you know the exact date of death of Schlaume Immermann, contact us via the contact page.
