Distinguishing features Filled

What robots and AI may and may not do Filled

Must not

  • Present a national day of one country as observed elsewhere.
  • Treat the abolition of slavery day as historical only, when forced labour persists today.
  • Convert 1804 or 1805 dates between calendars without saying which calendar is used.
  • Add on-this-day events without a source.

Only with a human decision

  • Publishing commemorative content for national days or for the slavery abolition day.

May

  • Report December 2 as day 336, or 337 in leap years, of the Gregorian calendar.
  • Relay national days and the International Day for the Abolition of Slavery with their origin and source.

Moral aspects Filled

  • Modern slavery still affects millions, so the commemoration carries present obligations.
  • National days matter to the people who observe them and should not be misstated.

Who is affected

  • People in forced labour
  • Citizens of the countries observing
  • Readers

Owners Filled

Steward

Nobody owns a date; the Gregorian calendar is held in common.
