The date of November 13 combines church celebrations, international initiatives, and folk customs. Believers celebrate the day of John Chrysostom (according to the new Julian calendar), the world celebrates the International Day of the Blind, and folk signs advise to carefully monitor the weather and words.
November 13 in the church calendar according to the new style is the day of Archbishop John Chrysostom, one of the most famous Christian preachers. According to the Julian tradition, on this day the martyr Peter the Long-Suffering, as well as the saints Nicodemus and Spyridon of Kiev-Pechersk, are honored. In folk pious practice, Chrysostom's day is associated with selfless help to others and a prayer for the forgiveness of sins and support in studies and work.
Internationally, November 13 is celebrated as International Day of the Blind: public organizations hold events that draw attention to the accessibility of urban spaces and modern rehabilitation tools. On the same day, the world remembers the importance of quality, usability, and good deeds - a number of initiatives are held under the names of Quality Day, Usability Day, and Kindness Day.
The date also has its historical context in Ukraine: in 1918, the UNR Directory was created, and in 1997, the first meeting of the Central Election Commission of independent Ukraine took place. Among the natives and anniversaries of the day are histologist Oleksandr Chernyakhivskyi, writer Ostap Vyshnya, composer Herman Zhukovskyi, mathematician Ihor Skrypnyk, and human rights activist, Crimean Tatar leader Mustafa Dzhemilev.
Folk signs traditionally focus on the weather: the joyful chirping of tits and sparrows portends warming; a cat looking for warm places - to frost; a fish jumping out of the water - to rain; thick morning fog - to prolonged precipitation. In everyday advice on this day, it is advised to help others selflessly, avoid harsh words and lies. It is also believed that journeys and affairs started on November 13 will have a good course - provided that they are brought to the end.
