Why isn't Ilja?last_name=Jakobson 's Yahrzeit Exact?

We do not know the exact date of death of Ilja?last_name=Jakobson . 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 Ilja?last_name=Jakobson on 8 Kislev. If you know the exact date of death of Ilja?last_name=Jakobson , contact us via the contact page.
