About Independence Day

Azerbaijan’s current law designates 28 May as Independence Day, and the official holiday register lists it as a day off.

The date is tied in current law to the 28 May 1918 Declaration of Independence by the National Council of the Azerbaijan Democratic Republic.

Why Independence Day matters

The current 28 May holiday name links the date to the 1918 Declaration of Independence referenced in Azerbaijan’s 2021 law.

The reviewed legal record also shows a later naming change from Republic Day to Independence Day; the 1918 event and the 2021 statutory change are therefore kept separate.

History of Independence Day

Before the 2021 naming law, an official 2021 Labour Code extract listed 28 May as Republic Day.

The Law on Independence Day dated 15 October 2021 declared 28 May Independence Day and separately named 18 October the Day of Restoration of Independence.

The current presidential holiday register uses the Independence Day name for 28 May.

The law’s date rationale refers to the 28 May 1918 Declaration of Independence; this historical event is distinct from the later statutory naming change.

The reviewed sources do not establish the original creation date or first recurring observance of the 28 May holiday.
