Why isn't Necha David's Yahrzeit Exact?

We do not know the exact date of death of Necha David. 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 Necha David on 18 Iyyar. If you know the exact date of death of Necha David, contact us via the contact page.
