Ekta Diwas, or National Unity Day, is celebrated every year on 31st October to honor Sardar Vallabhbhai Patel, the Iron Man of India. He played a vital role in uniting more than 560 princely states to form one strong and united India after independence. On this day, people take the Unity Pledge and participate in the Run for Unity to spread the message of harmony and national integration. Ekta Diwas reminds us of the importance of unity, peace, and working together for the progress of our nation.
