Tick Tock Day, also known as Still Need To Do Day, is observed annually on December 29. The observance centers on the reality that the year is nearly over, encouraging people to finish lingering tasks or consciously let go of what won’t be completed. Its name reflects the sound of a ticking clock, emphasizing that time is running out on the year and any unfinished goals tied to it.
The final days of December often reflect this transitional mindset. Some observances, like Tick Tock Day, emphasize wrapping things up to create clarity and mental space before January begins. Others take the opposite approach. The Festival of Enormous Changes at the Last Minute, observed on December 30, encourages action and last-minute beginnings, reminding people that meaningful change does not have to wait for the new year.

- The calendar we follow: The Gregorian calendar, introduced in 1582, reshaped how the year is measured and when it ends. Its gradual adoption helped standardize year-end dates across much of the world.
