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 Olive Tree Day is observed on 26 November. UNESCO established the Day to highlight the olive tree’s cultural, social, economic and environmental importance and its long-standing symbolism of peace, wisdom and harmony.
The observance also provides a practical entry point for discussing olive-growing landscapes, agricultural heritage, biodiversity, soil and water pressures, climate resilience and the livelihoods connected to olive cultivation.
Why it matters
Olive cultivation links living heritage with contemporary environmental and economic questions. Trees, groves, harvesting knowledge, foodways and trade can all carry cultural meaning while also depending on healthy soils, water systems and viable rural economies.
A useful observance therefore avoids treating the olive merely as a symbol. It can connect heritage protection with sustainable cultivation, responsible land management, scientific research and the knowledge of communities that maintain olive landscapes.
History
Lebanon and Tunisia submitted the proposal to proclaim 26 November as World Olive Tree Day. UNESCO’s Executive Board endorsed the recommendation at its 206th session.
On 26 November 2019, the UNESCO General Conference adopted 40 C/Resolution 49 and proclaimed 26 November of every year World Olive Tree Day. The resolution asks UNESCO’s Director-General to promote the Day and encourage activities around heritage protection and environmental sustainability.
The International Olive Council now describes itself as playing a central role in coordinating World Olive Tree Day celebrations with member-country delegations and other partners.
