Why isn't Mina Fainstein's Yahrzeit Exact?

We do not know the exact date of death of Mina Fainstein. 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 Mina Fainstein on 30 Kislev. If you know the exact date of death of Mina Fainstein, contact us via the contact page.
