This authority record treats the observance as a fixed annual date. The same month and day can be reused unless a stronger source changes the rule. Public-holiday or government status is never inferred from the observance name alone.
Overview
World No Tobacco Day is observed on 31 May under the World Health Organization. It focuses public attention on the health consequences of tobacco use, industry practices and evidence-based measures intended to reduce tobacco-related harm.
The observance can include cigarettes and other tobacco products, while current WHO campaigns may also discuss nicotine products. Permanent page content should distinguish enduring facts from annual campaign themes.
Why it matters
The day is not simply an instruction to quit for one day. Its broader purpose is public-health education, prevention, policy awareness and support for people who want to stop using tobacco or nicotine products.
Individual cessation needs differ. People seeking help should use qualified health services or evidence-based cessation resources rather than relying on generic observance content.
History
In 1987, the World Health Assembly adopted resolution WHA40.38 calling for 7 April 1988 to be observed as a world no-smoking day.
In 1988, the World Health Assembly adopted resolution WHA42.19 calling for World No Tobacco Day to be observed every year on 31 May. This is the recurring observance used today.
World Health Assembly resolution WHA42.19, adopted on 17 May 1989, established the recurring 31 May World No-Tobacco Day; this is kept separate from the one-off 7 April 1988 world no-smoking day.
