According to ТСН: December 23, 2025, is Tuesday. The 1398th day of war in Ukraine.

What holiday is tomorrow

Tomorrow, December 23, believers celebrate the Day of Remembrance of the 10 Martyrs of Crete. These martyrs lived on Crete when the island was under the control of pagan and Roman lords who persecuted Christians. They had unwavering faith and refused to sacrifice to pagan gods. As a result, they were arrested, tortured, and eventually executed. The Church honors them as holy martyrs who are a vivid example of devotion to Christ.

December 23 is also celebrated in Ukraine as the Day of Ukrainian Military Personnel of Operational Control at All Levels. This holiday recognizes the importance of operational control soldiers, staff specialists, and special communications troops of the Armed Forces of Ukraine. They work daily to coordinate and manage military operations, ensuring reliable communication and control at all levels. The holiday also commemorates the development of the Main Directorate of Special Communications of Ukraine, which was established in 1992 and is currently subordinate to the Security Service of Ukraine. This department provides special communication in state and military structures.

In addition, December 23 marks the Holiday of Human Light. This holiday was initiated in 2001 under the name HumanLight. It is not associated with the religious traditions of any particular faith, so it can be celebrated by people of various nationalities and worldviews. The name of the holiday contains the word 'light' in a metaphorical sense – it is the light of human reason, kindness, compassion, and hope. It reminds us to be kind, rational, responsible, and to support those who find themselves in difficult situations.

This year, especially in times of war, the holiday of Ukrainian military personnel takes on special significance, as the soldiers continue to defend their country. Greetings and respect for them on these days are not just a tribute to memory but also an expression of devotion and support. The Holiday of Human Light, in turn, serves as a reminder of the importance of humanity and supporting each other in difficult times.
