The Day of Declaration of Sovereignty is observed in Estonia every November 16, commemorating the Estonian Sovereignty Declaration of 1988. This significant event marked the assertion of Estonia's sovereignty and the supremacy of its laws over those of the Soviet Union. Although it is an official holiday established by the Parliament, employees do not receive a day off. The day is marked with official ceremonies throughout the country, reflecting on Estonia's historical journey towards independence, which began with its first declaration of independence in February 1918. This day also serves as a remembrance of the massive peaceful demonstrations against the Soviet regime that started in 1987, coinciding with the political reforms initiated by Soviet leader Mikhail Gorbachev. The anniversary of the Estonian Sovereignty Declaration is recognized as a key remembrance day in Estonia, highlighting the nation's resilience and commitment to its sovereignty.
