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
The International Day of UN Peacekeepers is observed on 29 May. It honours the service of military, police and civilian personnel in United Nations peacekeeping and remembers personnel who have lost their lives in the cause of peace.
The page distinguishes recognition of peacekeeping personnel from the broader International Day of Peace and from current operational claims about any particular mission.
Why it matters
United Nations peacekeeping involves international mandates, host-country contexts and personnel serving in very different roles. Recognition should therefore avoid portraying all missions, conflicts or communities as interchangeable.
Current mission mandates, deployments and security conditions can change and should be checked against the United Nations if discussed.
History
The General Assembly designated 29 May as the International Day of United Nations Peacekeepers through resolution 57/129.
The United Nations explains that 29 May was chosen because the first UN peacekeeping mission, the United Nations Truce Supervision Organization, began operations on that date in 1948.
