Why isn't Abram Seif's Yahrzeit Exact?

We do not know the exact date of death of Abram Seif. 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 Abram Seif on 15 Av. If you know the exact date of death of Abram Seif, contact us via the contact page.
