Held on 1st -7th July
Van Mahotsav literally stands for ‘Forest' (van) and ‘Festival' (mahotsav). It is a Hindi Word which means ‘Tree Festival’. This tree planting festival is observed annually, over a period of week starting form 1st July to 7th July. It’s is celebrated to raise awareness among the masses about the importance of trees, their plantation and conservation. 
It was initiated in 1950 by K. M. Munshi, the then Union Minister for Agriculture and Food to create an enthusiasm in the mind of the populace for the conservation of forests and planting of trees. The first ever national awakening to the necessity of planting trees and attempts at tree rehabilitation on a national scale came in July 1947, with a successful tree plantation drive in Delhi. Such drives are now conducted around the whole country. On this day educational institutes organise various events like planting saplings, awareness walk, screening of documentaries etc. Similar activities are also undertaken by governmental and concerned private organisations. Other activities include exhibitions, seminars, distribution of free saplings to citizens and so on.
