Why isn't Gutman Hillman's Yahrzeit Exact?

We do not know the exact date of death of Gutman Hillman. 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 Gutman Hillman on 16 Shevat. If you know the exact date of death of Gutman Hillman, contact us via the contact page.
