Uttar Pradesh organised 'UP Day 2026' from January 24 to 26, 2026, to commemorate the historic occasion when the state was renamed from 'United Provinces' to 'Uttar Pradesh' on January 24, 1950 — just two days before India's Constitution came into force on January 26, 1950. The three-day event showcased UP's rich cultural heritage, artisanal traditions, developmental achievements, and economic progress. Celebrations were held both across India and abroad, reflecting the state's growing soft-power footprint. The state of Uttar Pradesh — with a population exceeding 240 million — is India's most populous state and has emerged as one of the fastest-growing economies among Indian states, with ambitions to become a $1 trillion economy. Key areas highlighted during UP Day 2026 included the state's transformation in infrastructure (Expressways, UDAN airports), industrial investment (UP Global Investors' Summit), and tourism growth around its spiritual and cultural circuit including Prayagraj, Varanasi, Mathura-Vrindavan, and Ayodhya. The occasion also held historical resonance with the 77th Republic Day on January 26, 2026.
