The short answer: in many places the common etiquette is to wear a poppy from late October through Remembrance Day on November 11, and some people continue wearing it for commemorative occasions or at funerals of veterans. When to stop varies by tradition and personal choice, with many people taking it off after Remembrance Day or after the Remembrance ceremony on Remembrance Sunday, while others keep it on longer or year-round as a personal gesture. If you’d like, I can pull up official guidance from specific organizations for precise dates in your country. Guidance by region (general patterns)

• Canada: The national guidance from veterans organizations typically designates the Remembrance period as late October through November 11, with poppies worn for commemorative events and funerals as appropriate. People often remove the poppy after Remembrance Day (Nov 11) or after the Remembrance ceremony, and some choose to place their poppy on a cenotaph or wreath as a sign of respect.

• UK and Commonwealth: The poppy is traditionally worn from late October through Remembrance Sunday (the second Sunday in November) and commonly removed after the Remembrance ceremony; some individuals keep it on for the remainder of the week or until the end of November 11th commemorations.

• Personal choice and exceptions: Many people wear poppies at commemorative events (funerals of veterans, memorial services, anniversaries such as Vimy Ridge) and some wear them year-round as a personal tribute.

Practical etiquette tips

• Placement: Wear on the left lapel over the heart; ensure it is visible but not obstructive.

• Removal: Some people remove the poppy at the end of the day on November 11, others after the Remembrance ceremony; some place the poppy on a cenotaph or wreath as a sign of respect.

• Multiple wearers: If you are attending multiple commemorative events, you can wear a poppy for those events and remove it afterward if you choose; some organizations encourage continued remembrance beyond the formal period via funeral or memorial participation.

If you specify your country or community, the exact dates and recommended practices can be confirmed with official guidance from the relevant veterans’ association or legion.
