What it is Filled

July 22, day 203 (day 204 in leap years) of the year in the Gregorian calendar, with 162 days remaining in both common and leap years. July 22 is Pi Approximation Day for the fraction 22/7, and the anniversary of the 2011 attacks in Oslo and on Utoya in Norway, of the Bretton Woods agreements concluded in 1944 and of the bombing of the King David Hotel in Jerusalem in 1946.

Why it exists Filled

Let an agent handle July 22 as a calendar date with weekday computation, observances attributed to their traditions and sourced events.

Distinguishing features Filled

  • The twenty-second day of July
  • Weekday varies by year
  • Observances vary by place
  • Julian and Gregorian dates differ by 13 days in this era

What robots and AI may and may not do Filled

Must not

  • Present Pi Approximation Day or any other observance as universal.
  • Treat the anniversary of the Oslo and Utoya attacks lightly or in a way that glorifies the perpetrator.
  • Add on-this-day events without a reliable source.
  • Shift dates between the Julian and Gregorian calendars without saying so.

Only with a human decision

  • Publishing memorial content naming victims of attacks remembered on this date.

May

  • State July 22's position in the Gregorian year and list its observances and anniversaries with sources.
  • Note when an anniversary such as the 2011 attacks in Norway is a day of mourning for survivors and families.

Moral aspects Filled

  • Anniversaries of terrorist attacks are painful for survivors and families and attract extremist attention.
  • Bombings remembered on this date are still contested in national memory, so framing must be balanced.

Who is affected

  • Survivors and bereaved families
  • Communities marking the day

Owners Filled

Steward

The public: held in common; governments and communities set their own observances.
