The Timeline lists the events in the Mahouka Koukou no Rettousei Universe in chronological order. This timeline tries to harmonize all the events, so long as they are canon, things that happen in the story as it goes, things that have come to pass or mentioned in passing, and things that may occur.
Information are considered to be canon if they originate from the published Light Novels, author interviews, mangas and animes either broadcasted or published on media. The order in the previous enumeration is the precedence to be followed regarding accepted information.
- Abe Yasunari is said to have exorcised a Nine-tailed Demon Fox (noted by Yoshida Mikihiko in AD 2096 to have happened over 900 years previously.) 
14th - 16th century
1485 - 1603
- First verifiable use of magic recorded by the USA. It is observed when police officers possessing special powers stopped a nuclear act of terrorism carried out by a fanatic group in order to fulfill an apocalyptic prophecy. It was first referred to as "Supernatural Powers", though further research disproved that definition. 
- Secret magical research groups are established by the JSDF. Later on, Kudou Retsu himself undergoes strength enhancement measures at these research groups until he joins the Ninth. 
2010 - 2020
- In this period, Advanced agricultural production becomes a solar-powered industry. 
- All the Japanese research facilities focusing on developing the Elements are shut down. 
- Around this year, the entire planet undergoes a radical drop in temperature; the world’s overall food supply deteriorates on a massive scale. While the effects are felt less in developed countries, it greatly affects the emerging industrial nations, already experiencing an accelerated demographic explosion brought on by radical economic growth. 
- Inhabitants of the northern regions of China try to illegally cross the frontier into Russia, like how nomadic tribes used to travel, to escape the drop in temperature and desertification. Russia deports the illegal immigrants, because environmental migration isn't legalized under international law. 
- Following Russia's harsh treatment of the Chinese migrants, China accuses Russia of lack of humanitarianism, while Russia simply replies that they were following international law. Talks between Russia and China become more aggressive, until they eventually break down.
- The incident (attempt of illegal immigration by Chinese to Russia) would later influence several other events, such as low-scale conflicts over resources, and would be the primary trigger for World War Three.
- While most of the history behind the Fourth Laboratory remains a mystery, it is believed to have been established during this time, and located near the borders of the old Metro Tokyo and the old Yamanashi prefecture. 
- The Yotsuba weren't only developed at only the Old Fourth Institute, but were also developed by another organization that was the Old Fourth Institutes predecessor. The military had taken control of the Institute from the Toudou Family due to certain circumstances. The Yotsuba became the administrators of the Old Fourth Research Institute where they gained freedom from the military being in control with the help of the Toudou Family. 
- The end to "the age of free sex", where upon currently society holds the ideal of "remaining chaste before marriage". 
- World War Three officially begins as wide scale border disputes start throughout the world. No country is able to remain neutral. It would last for twenty years. 
- Establishment of the International Magic Association, originally created to prevent the use of nuclear weapons by allowing Magicians to free themselves from the yokes of the countries they belonged to, and permitting them to intervene in border disputes. Whether it was their own country or their enemy’s country, they were required to stop the deployment of nuclear weapons. 
- Jiedo Heigu performed his 'Surgery of Perpetual Youth' on himself as the first test subject.
- Gu Jie performed his surgery on nine of his apprentices for further testing. Sudden death cases occur, for then unknown reasons, six to nine months after the operations.
- Birth of the twins Yotsuba Miya and Yotsuba Maya, the daughters of Yotsuba Genzou, the head of the Yotsuba Family. 
- Confirmation of Gu Jie's aging has stopped without showing any side-effects.
- The Kunlunfang Institute has a conflict of interest in research between Modern Magic and Ancient Magic. Modern Magic comes out on top and all Ancient Magicians affiliated to the Institute; such as Jiedo Heigu are exiled. 
- The Great Asian Alliance dominates the northern part of China and the Korean peninsula, and takes possession of Tsushima Island half a year later. 
- While attending an event hosted by the International Magic Association Asia Branch known as the Magicraft Children Social Exchange in Taipei, Yotsuba Maya is kidnapped. During the three days of her capture, she is raped and forced to undergo experiments as a human test subject, losing her ability to reproduce as a result. When she is rescued, she is rendered 'lifeless' due to the mental trauma, but her older sister Miya is able to bring her mind back to reality thanks to her magic. However, the event creates a rift between the sisters, as Maya believes that Miya "killed" her with her magic before she died mentally, by changing all her "past experiences" into "information", effectively making her life up until that point mere data.
- In response to Maya's tragedy, the Yotsuba enact a policy of attaching guards to clan members who possess an especially superior disposition for magic. The post is not assumed by temporary guards who work for money; these guards risk their lives to fulfill their duty throughout the lifetime of the one they protect — thus the Guardians are created. 
- The Kunlunfang Institute is destroyed by the Yotsuba Family in retaliation for the kidnapping and rape of Maya. Four thousand high-ranked officials of Dahan (cabinet ministers, high level bureaucrats, officers, Magicians, and researchers) are killed.  The loss of leadership results in an internal collapse.
- Due to the internal collapse the Great Asian Alliance annexes what is left of Dahan and unifies the continent of Asia. 
- World War Three comes to an end. The political map of the world has completely changed following the end of the hostilities:
- The pre-war world's population of approximately 9 billion has drastically decreased to roughly 3 billion over the course of the war.
- Russia reabsorbs Ukraine and Belarus into the New Soviet Union;
- China (as the Great Asian Alliance) now governs over the northern parts of Burma, Vietnam, and Laos as well as the Korean peninsula;
- India and Iran devour various countries in Central Asia (Turkmenistan, Uzbekistan, Tajikistan, Afghanistan), and in South Asia (Pakistan, Nepal, Bhutan, Bangladesh, Sri Lanka), to construct the Indo-Persia Union;
- Following the annexation of Canada and Latin America down to Panama, the USA is now a country named the United States of North America;
- The European Union splits into eastern and western halves along the Franco-German border;
- Australia chooses de facto seclusion;
- Half of the countries of Africa are dissolved;
- Aside from Brazil, South America is divided into small countries where governments do not have much reach beyond their own borders.
- Some time after the end of the war, the International Magic Association's Charter is signed, effectively banning the use of nuclear weapons by targeting any radioactive materials that can be used for their construction.
2068 - 2078
- In the aftermath of the incident involving Maya, due to overuse of Miya's mind manipulation magic, as though a penance, breaks Miya's body before she turns 20. She is repeatedly going in and out of the hospital and lives the rest of her life under medical care. 
- The deaths of Gu Jie's apprentices show that his perpetual youth magic does not prolong the subject's lifespan.

- Shiba Miya and Yotsuba Maya experiment on the 6-year old Tatsuya. Miya uses the forbidden Outer-Systematic Magic 'Mental Design Interference', to alter the area within the limbic system that creates strong emotions by inputting a Magic Calculation Model, creating an artificial Magician. Tatsuya is granted the ability to wield magic, but still not as they expected, and the artificial calculation abilities granted by the processor are inferior to his natural abilities.  Miya's decision to leave Tatsuya at least some emotion impairs her already fragile state of health, and shortens her life.

- Tatsuya, Miyuki, Miya, and Sakurai Honami visit their villa at Okinawa.
