Why isn't Georg Gerson's Yahrzeit Exact?

We do not know the exact date of death of Georg Gerson. 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 Georg Gerson on 14 Tishri. If you know the exact date of death of Georg Gerson, contact us via the contact page.
