Why isn't Maria Klatzko's Yahrzeit Exact?

We do not know the exact date of death of Maria Klatzko. 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 Maria Klatzko on 18 Sivan. If you know the exact date of death of Maria Klatzko, contact us via the contact page.
