Lord Shiva, affectionately known as Bholenath, Mahadev, Neelkanth and more, worshipping the deity on Mondays has traditional roots. Devotees also observe a fast on Monday, often known as Someshwar Vrat. To make Mondays even more spiritual and mark a devotional start to the week, devotees share Lord Shiva photos and 'Om Namah Shivaya' pictures.
