Why isn't Israel Lutrin's Yahrzeit Exact?

We do not know the exact date of death of Israel Lutrin. 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 Israel Lutrin on 27 Tammuz. If you know the exact date of death of Israel Lutrin, contact us via the contact page.
