Why isn't Sara Michelson's Yahrzeit Exact?

We do not know the exact date of death of Sara Michelson. 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 Sara Michelson on 22 Shevat. If you know the exact date of death of Sara Michelson, contact us via the contact page.
