Why isn't Herschel Schense's Yahrzeit Exact?

We do not know the exact date of death of Herschel Schense. 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 Herschel Schense on 28 Tevet. If you know the exact date of death of Herschel Schense, contact us via the contact page.
