Parents' Worship Day
Parents' Worship Day, known as Matru Pitru Poojan Diwas (Hindi: मातृ-पितृ पूजन दिवस, also "Matru Pitru Poojan Divas") was started by the Indian spiritual leader Asaram Bapu in 2007 as an alternative to Valentine's Day which Bapu sees as non-Indian. It is based on the Sanskrit words for mother (मातृ, "mātṛ") and father (पितृ, "pitŕ").
