Why isn't Jankel Schalminis's Yahrzeit Exact?

We do not know the exact date of death of Jankel Schalminis. 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 Jankel Schalminis on 14 Kislev. If you know the exact date of death of Jankel Schalminis, contact us via the contact page.
