How it shows up in everyday life
This explains why India has two significant constitutional dates: 26 November (Constitution Day, when the Assembly adopted the final text) and 26 January (Republic Day, when it actually came fully into force) — and it's specifically why the choice of 26 January mattered: that was the same date the Indian National Congress had declared 'Purna Swaraj' (complete independence) back in 1930, giving the Republic's birth deliberate historical symbolism.
