Republic Day honours the date on which the Constitution of India came into effect on 26 January 1950 replacing the Government of India Act (1935) as the governing document of India.
The Constitution was adopted by the Indian Constituent Assembly on 26 November 1949, and came into effect on 26 January 1950 with a democratic government system, completing the country's transition towards becoming an independent republic. 26 January was chosen as the Republic day because it was on this day in 1930 when Declaration of Indian Independence (Purna Swaraj) was proclaimed by the Indian National Congress as opposed to the Dominion status offered by British Regime.
It is one of three national holidays in India, the other two being Independence Day and Gandhi Jayanti.

In 2006 the Council of Europe launched a Data Protection Day to be celebrated each year on 28 January, the date on which the Council of Europe's data protection convention, known as "Convention 108", was opened to signature. Data Protection Day is now celebrated globally and is called Privacy Day outside Europe.
On this date, governments, parliaments, national data protection bodies and other actors carry out activities to raise awareness about the rights to personal data protection and privacy. These may include campaigns targeting the general public, educational projects for teachers and students, open doors at data protection agencies and conferences.
The data protection convention, which is the only international treaty in this field, is being updated to ensure that its data protection principles are still in line with today's needs.
