How to use this tool
Begin with the date of death, not the date on a civil anniversary reminder. Enter burial information when your first-year custom uses it. Adar and short-month rules vary; use the choices supplied by your family or rabbi. An unresolved 30 Adar I case is flagged instead of guessed.
A practical example
January 7, 2020, before sunset is 10 Tevet 5780. The 5787 anniversary falls on December 20, 2026, beginning the previous evening.
