Why isn't Schepsel Weichslin's Yahrzeit Exact?

We do not know the exact date of death of Schepsel Weichslin. 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 Schepsel Weichslin on 20 Tevet. If you know the exact date of death of Schepsel Weichslin, contact us via the contact page.
