National Father’s Day
National Father’s Day in Thailand is celebrated on December 5th, the birthday of His Majesty King Bhumibol Adulyadej, who is lovingly remembered as the “Father of the Nation.” On this special day, families express gratitude for fathers’ love, sacrifice, and guidance. A meaningful tradition is the giving of the Canna flower (Dok Phuttharaksa), symbolizing strength and devotion.
At Concordian International School, we warmly organized special activities at each educational level to honor His Majesty and celebrate Father’s Day, fostering gratitude, respect, and appreciation within our school community.

EY Father’s Day
Early Years Students have learned the importance of “Father’s Day” “วันพ่อแห่งชาติ” and “Thai National Day” “วันชาติ” on December 5th. They’ve listened to a story of the Great King Rama IX, and a lovely story about a father and each grade level has created their own special Father’s Day cards. We also displayed their father’s picture artworks at the school lobby.





PY Father’s Day singing event 2025
This year, we were pleased to present singing performances by all PY G1–G5 classes in celebration of Father’s Day, held from December 2nd–4th, 2025, in the main lobby.
For this performance, we have selected a number of musical compositions created in tribute to the immeasurable royal benevolence of His Majesty King Bhumibol Adulyadej the Great, the Late King Rama IX, including "Sanya Duay Jai" (Promise From the Heart, a song composed by Concordian).
On that day, the lobby was filled with proud parents, many of whom stood along the stairways and on the second floor, listening attentively and capturing their children’s performances. The students sang with clear, resonant voices and genuine emotion, sharing their music with confidence and pride. Their voices created a truly heartwarming experience that reflected profound loyalty, deep gratitude for His graciousness, and the enduring bond between the Thai people and their beloved monarch. It was a truly memorable and deeply touching moment for all of us.

Secondary Father’s Day Activities
To commemorate the immeasurable benevolence of His Majesty King Bhumibol Adulyadej the Great (Rama IX), this year’s Father’s Day activities for secondary students were conducted as classroom-based learning activities. The focus was on helping students understand His Majesty’s life, royal duties, and passing, as well as the significance of Father’s Day and the traditions observed annually by the Thai people.
Students studied the royal biography, major royal projects, and His Majesty’s lifelong dedication to the nation's well-being. They also learned about the importance of Father’s Day as a national occasion that reflects gratitude, unity, and respect. As part of the learning process, students watched the video “The King’s Philosophy: Wisdom of the Land” to deepen their understanding of His Majesty’s principles and development philosophy.
In addition, students conducted research on royal speeches delivered by His Majesty King Bhumibol Adulyadej the Great. Each student selected a royal speech that they found meaningful or inspiring and wrote a reflection titled “Applying the Royal Teachings in Daily Life.” Through this activity, students explored ways to apply His Majesty’s guidance in their daily lives, fostering critical thinking, moral awareness, and a sense of personal responsibility.
Beyond classroom learning, students also participated in performances to honor Father’s Day. Student representatives performed the song “ความฝันอันสูงสุด” (The Impossible Dream) at the school lobby in the morning. In the evening, students further took part in the Foundation of Love performance, expressing respect, gratitude, and unity through artistic expression.
Overall, these activities provided students with meaningful opportunities to deepen their historical understanding, reflect on core values, and appreciate the lasting legacy of His Majesty King Bhumibol Adulyadej the Great.
