Science Day is a national day and an annual event that falls on April 16 of each year in Algeria and is celebrated to glorify the scientists who spread science. It marks the day of the death of the Algerian scholar Abdelhamid Ibn Badis

The Algerian state holds a group of programs and celebrations on the occasion of Science Day

National Science Day was established in honor of the struggle of Imam Abdelhamid Ben Badis (1889-1940) at the initiative of President Houari Boumediene “to remind Algerians of the advantages of science.” It was celebrated for the first time in 1976.

The president’s speech stated the following: “It is not possible to subjugate an educated man, just as it is impossible to subjugate a people who are drawn to the sources of knowledge. For this reason, it may be wise to establish a Science Day to be celebrated every year in school institutions and the media to remind Algerians of the advantages of science.”

Abd al-Hamīd ibn Mustafa ibn Makki ibn Badis (Arabic: عبد الحميد بن مصطفى بن المكي بن باديس), better known as ابن باديس (Arabic: عبد الحميد بن باديس (December 4, 1889 – April 16, 1940) was an Algerian educator, exegete, Islamic reformer, scholar and figurehead of cultural nationalism. In 1931, Ben Badis founded the Association of Algerian Muslim scholars, which was a national grouping of many Islamic scholars in Algeria from many different and sometimes opposing perspectives and viewpoints. The Association would have later a great influence on Algerian Muslim politics up to the Algerian War of Independence. In the same period, it set up many institutions where thousands of Algerian children of Muslim parents were educated. The Association also published a monthly journal, the Al-Chihab and Souheil Ben Badis contributed regularly to it between 1925 and his death in 1940. The journal informed its readers about the Association's ideas and thoughts on religious reform and spoke on other religious and political issues.
