Short answer: In many countries that observe Remembrance Day, poppies are traditionally worn during the Remembrance period (typically from the last Friday in October through November 11) and sometimes into Remembrance Sunday or the end of Remembrance Day ceremonies. After that, wearing a poppy is a personal choice, and many people remove it after the day/ceremony, or place it on a cenotaph as a sign of respect. If you’re unsure, follow the guidance of your local veterans’ organization or institution. Details and guidance

• When to wear
  • Canada and the UK commonly advocate wearing the lapel poppy from the last Friday in October until November 11, with some people keeping it on through Remembrance Sunday or the end of Remembrance Day ceremonies. Some institutions also encourage poppies at funerals or commemorative events.

• How long to wear
  • There is no universal rule requiring you to wear it year-round; many wear it only during the Remembrance period or the day itself, and some choose to continue for a memorial service or special anniversary events.

• Etiquette considerations
  • If you attend a remembrance ceremony or funeral, wearing a poppy is appropriate. If you feel it’s no longer appropriate in a given setting, you may remove it and, if desired, place it on a cenotaph or wreath as a sign of respect.

Quick references (for your context)

• Official guidance from veterans organizations generally frames the poppy as a symbol to be worn during the Remembrance period and at related ceremonies, with flexibility for personal choice.

• Community and forum discussions reflect varying practices, including removing after Remembrance Day or keeping it longer for personal reasons. These are cultural norms rather than strict rules.
