Why isn't Rachmiel Manuchowitz's Yahrzeit Exact?

We do not know the exact date of death of Rachmiel Manuchowitz. 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 Rachmiel Manuchowitz on 25 Kislev. If you know the exact date of death of Rachmiel Manuchowitz, contact us via the contact page.
