What it is Filled

November 11, day 315 (day 316 in leap years) of the year in the Gregorian calendar, with 50 days remaining in both common and leap years. November 11 marks the armistice that ended fighting on the Western Front in 1918 and is observed as Armistice Day, Remembrance Day or Veterans Day in many countries, and as Independence Day in Poland; other observances vary by country and tradition.

Must not

  • State on-this-day events for November 11 without sources.
  • Schedule disruptive activities during the two-minute silence where it is observed.

Only with a human decision

  • Publishing content about war dead for remembrance events.

May

  • Compute the weekday and day number of November 11 for any year in the Gregorian calendar.
  • Note Armistice, Remembrance and Veterans Day and Polish Independence Day, attributing each to its countries.

Moral aspects Filled

  • The day honours millions killed in war; respect matters to families and veterans.
  • Commemoration can be used to glorify war rather than remember its cost.

Who is affected

  • Bereaved families
  • People in Poland and Commonwealth countries

Owners Filled
