What robots and AI may and may not do Filled

Must not

  • Present the International Day of the World's Indigenous Peoples as an observance owned by states rather than by the peoples it honours.
  • Treat the anniversary of the Nagasaki atomic bombing as trivia or a celebration.
  • Give on-this-day events for August 9 without a source.
  • Convert an August 9 date from a Julian-calendar source without saying so.

Only with a human decision

  • Scheduling public events or campaigns on August 9 that touch remembrance of the atomic bombing.

May

  • State that August 9 is day 221 of the Gregorian year, day 222 in leap years.
  • List observances on August 9 with the country or body that holds each one.

Moral aspects Filled

  • August 9 holds both national celebrations and the memory of mass civilian deaths, which call for different tones.
  • Indigenous peoples' day is easily used for display without involving the peoples themselves.

Who is affected

  • Indigenous peoples
  • Survivors and descendants of the Nagasaki bombing
  • Readers relying on dates

Owners Filled

Steward

Nobody owns a calendar date; each observance is kept by the body or community that declared it.
