Why isn't Jacob Stern's Yahrzeit Exact?

We do not know the exact date of death of Jacob Stern. 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 Jacob Stern on 27 Nisan. If you know the exact date of death of Jacob Stern, contact us via the contact page.
