The doctor cannot diagnose the disease. This is the reality for many rare disease patients. Lack of scientific knowledge and quality information about the disease often leads to delays in its diagnosis. Without adequate quality of medical care and difficulties in accessing treatment and care, the patient faces a heavy social and financial burden. Studying this problem could lead to the identification of previously unknown diseases and help improve understanding of the rare disease. This will allow doctors to make the correct diagnosis and provide the patient with comprehensive information about his disorder. International Rare Disease Day is celebrated around the world on the last day of February every year. The main objective of the day is to raise awareness among the general public and those in power who decide to study little-known manifestations of illnesses and their impact on the life of the patient. The campaign aims to raise awareness among policymakers, government agencies, industry, researchers, healthcare professionals and those with an interest in little-known diseases. Rare Disease Day was first launched by EURORDIS and its National Alliance Council in 2008. The campaign began as a European event and gradually spread throughout the world. Some countries, such as Spain, have decided to raise global awareness of little-known diseases by declaring the entire year National Rare Disease Year. For a dozen years, thousands of events around the world have been dedicated to this day, involving hundreds of thousands of people. During the last week of February, thousands of people from around the world will come together to advocate for more research into rare diseases. In recent years, the number of foundations and organizations conducting such research has increased significantly. They do not want to stop there, but constantly find the necessary funds to conduct independent or partner research projects. Innovative approaches to rare disease research will benefit not only those suffering from the disease, but also the general public.

Programmers and IT specialists have many professional holidays. One of them, International Overclockers Day, was invented in 2004 in Russia, but is celebrated all over the world. The dream of every computer geek is to overclock (in English - overclocking) the processor of his PC to increase performance to unprecedented speeds. Therefore, on the last day of February, Overclocker Day is celebrated - a holiday of technical enthusiasts who are not afraid to experiment with hardware and constantly conquer new heights. The idea of ​​International Overclockers Day originated at a computer forum in Leap Year 2004. The date of the celebration was set for February 29, when the month seems to accelerate by one day once every 4 years. Some programmers claim that the approach of spring creates a positive mood and inspires new achievements. One of them is “hardware overclocking,” which translated from professional slang means increasing the power parameters of a personal computer. For this purpose, computer scientists “raise” the frequency of the processor or video card above the factory settings. Overclocking hardware is also achieved by increasing the operating voltage of PC components or installing advanced cooling systems. Yes, many equipment manufacturers produce video cards with chips with automatic factory overclocking. However, there is no limit to perfection - increasing computer performance. Some enthusiasts use liquid nitrogen for extreme CPU cooling, while others saw off the back of the video card to install a special 500-amp power system. To speed up your PC, all means are good. Veteran overclockers are participating in professional competitions on February 28 and 29, demonstrating their skills in overclocking hardware to unprecedented speeds. IT specialists all over the world celebrate the Days of Safe Internet and System Administrator, Programmer and Tester, Computer Science and Freedom of Speech on the Internet. These holidays are very important for professionals who cannot imagine their lives without computers and home computers. In February 2004, a visitor to the forum of a Russian overclocking portal suggested setting a day for another celebration that quickly became international - International Overclockers Day. After some discussion, the date was chosen - February 29 in a leap year or February 28 in a regular year. Since then, the holiday of hardware overclocking masters has been celebrated - Overclocker's Day.
