Why isn't Mere Glaser's Yahrzeit Exact?

We do not know the exact date of death of Mere Glaser. 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 Mere Glaser on 5 Shevat. If you know the exact date of death of Mere Glaser, contact us via the contact page.
