Why isn't Schmuel Rubin's Yahrzeit Exact?

We do not know the exact date of death of Schmuel Rubin. 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 Schmuel Rubin on 22 Elul. If you know the exact date of death of Schmuel Rubin, contact us via the contact page.
