Why isn't Dobe Michelson's Yahrzeit Exact?

We do not know the exact date of death of Dobe Michelson. 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 Dobe Michelson on 29 Elul. If you know the exact date of death of Dobe Michelson, contact us via the contact page.
