Why isn't Aron Meilach's Yahrzeit Exact?

We do not know the exact date of death of Aron Meilach. 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 Aron Meilach on 18 Sivan. If you know the exact date of death of Aron Meilach, contact us via the contact page.
