Why isn't Itzig Rottermund's Yahrzeit Exact?

We do not know the exact date of death of Itzig Rottermund. 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 Itzig Rottermund on 29 Kislev. If you know the exact date of death of Itzig Rottermund, contact us via the contact page.
