In 1918, the Russian Empire, which included Estonia at the time, transitioned from the Julian calendar to the Gregorian calendar. This change was significant as Russia had retained the Julian system established by Julius Caesar for centuries, long after the rest of Europe had adopted the Gregorian calendar. The October Revolution marked the turning point for this transition, as the new calendar meant that November events in the past would have actually occurred two weeks earlier on the Julian calendar, ultimately resulting in the loss of 14 days in the transition.

As a result of this calendar reform, January 31, 1918, was immediately followed by February 14, leading to a peculiar gap in time. The article highlights several notable events that occurred on February 14 throughout the years. For instance, in 1911, agricultural courses were launched by the Estonian Farmers' Society in Tartu, indicating a focus on agricultural education and development. The mention of events from the Winter Olympics in 1928 and the first public ice hockey game in Tallinn in 1932 further emphasizes Estonia's cultural and sporting history during these dates.

This shift not only marked a transformation in how time was recorded and perceived in Estonia but also reflected the broader historical changes that accompanied the fall of the Russian Empire and the emergence of new national identities. The article serves to remind readers of the historical significance behind these seemingly mundane calendar changes, encapsulating the intersection of cultural evolution and national development.
