Ganesh Chaturthi is a very big festival celebrated throughout India–in the recent times, the celebration and rituals involving ‘Ganpati Visarjana’, which means taking the idols of Lord Ganesha in processions and then immersing them in nearby water-bodies (maybe the ocean, seas, rivers, or even canals), has become popular in North Indian states including Punjab and Haryana too.
The day marks the fourth day of the lunar fortnight–the festival usually goes for 10 days, whereby the installed idols of the Lord Ganesha are immersed in the water on the 10th day.
