Why isn't Hillel Klompus's Yahrzeit Exact?

We do not know the exact date of death of Hillel Klompus. 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 Hillel Klompus on 12 Shevat. If you know the exact date of death of Hillel Klompus, contact us via the contact page.
