Tac Ka Coong Festival is a celebration held by the Co Tu ethnic people to offer thanks to the gods of mountains, forests, rivers and streams within the village, for bestowing upon their descendants a life of warmth, happiness, prosperity, bountiful harvests, and good health.

On the morning of January 1, at Ngo Mon Gate - Hue Imperial Citadel, the Provincial People's Committee organized the announcement of Hue Festival 2023 with the first activity being the re-enactment of the Nguyen Dynasty Ban calendar distribution ceremony.

In the past, at the end of each lunar year, the Nguyen Dynasty would hold the Ban Soc ceremony (also known as the Calendar Distribution ceremony) to issue the new calendar to the people.
