Why isn't Etl Ulmann's Yahrzeit Exact?

We do not know the exact date of death of Etl Ulmann. 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 Etl Ulmann on 12 Adar. If you know the exact date of death of Etl Ulmann, contact us via the contact page.
