Yusnier Viera established a world record for calendar calculations on October 31, 2005, marking his entry into the field of competitive mental mathematics. Born in Bejucal, Cuba, in 1982, Viera pursued his academic development at the University of Havana before moving to the United States to continue his work as a mental calculator and mathematician.
Calendar Calculation Records
Often referred to as 'The Human Calendar,' Viera gained international attention for his ability to calculate dates at high speeds. Between 2005 and 2015, he secured six Guinness World Records. His most notable proficiency lies in the volume of calculations performed within a sixty-second window, reaching a peak performance of 132 calendar dates. He further solidified his status in 2010 by winning the calendar category at the Mental Calculation World Cup.

Viera has featured on several international broadcast networks, including CNN and ABC. He also performed demonstrations on 'The Ellen DeGeneres Show.'
Neuroscientific Analysis
Researchers at the University of Sussex conducted a study involving Viera to understand the neurological basis of his abilities. Using fMRI scans and the Raven's Progressive Matrices Test, they assessed his cognitive performance and brain activity. The study concluded that his mental calculation skills stem from a combination of sustained motivation and extensive, long-term practice rather than innate neurological anomalies.
Academic Publications
Beyond his competitive career, Viera has transitioned into education through the publication of instructional materials. He is the author of 'Basic Course of Mental Arithmetic' and 'Master the Multiplication Tables,' both of which aim to teach his methods for rapid numerical computation to a broader audience.
