  • Assume an observance on December 14 holds everywhere.

Only with a human decision

  • Scheduling a binding deadline on December 14 where local holidays are not confirmed.

May

  • List anniversaries such as Amundsen reaching the South Pole in 1911, citing sources.

Moral aspects Filled

  • Anniversaries shape how people remember history, so they should be sourced.
  • Polar exploration history includes disputes over credit that should be presented fairly.

Who is affected
