Establishment Day, formally the Hong Kong Special Administrative Region Establishment Day (Chinese: 香港特別行政區成立紀念日), is celebrated annually on 1 July in Hong Kong, China since 1997. The holiday celebrates the transfer of sovereignty over Hong Kong from the United Kingdom to the People's Republic of China and the establishment of the Hong Kong Special Administrative Region. The similarly-named holiday in Macau occurs on 20 December, the day of its handover from Portugal.
