December 29 Holidays

International Cello Day celebrates the cello — the tenor and bass voice of the string family, whose range spans more than four octaves and whose repertoire includes Bach’s Unaccompanied Suites, Dvorak’s Cello Concerto, and Elgar’s Cello Concerto — each a cornerstone of the orchestral and chamber canon. Mongolia Independence Day marks December 29, 1911, when Mongolia declared independence from China’s Qing dynasty — the formal founding of an independent Mongolian state on the Mongolian Plateau, homeland of the Mongol Empire that once controlled the largest contiguous land empire in history. Still Need To Do Day was established as a pre-New Year’s reflection day — encouraging people to review the tasks, promises, and goals they set at the start of the year and assess whether there is still time to complete any of them before midnight on December 31. Tick Tock Day was created to mark the final two days of the year — the 364th and 365th — with the urgent awareness that the year’s remaining hours for completing unfinished resolutions are dwindling.
