One of the most significant festivals for Hindus is Maha Shivaratri. The day is devoted to Lord Shiva and is observed with lavish celebrations all over India. On this day, devotees observe a fast and worship Lord Shiva to enlist his blessings. On Maha Shivaratri, it is believed that fasting and worshipping Lord Shiva for just one day will bring you blessings for a lifetime.

Every year, the Hindus commemorate Maha Shivaratri, also known as Mahasivaratri in Sanskrit, as a holiday in honour of the god Shiva. The term also alludes to the night when Shiva is thought to dance the Tandava, a celestial dance.

Every luni-solar Hindu month has a Shivaratri, or "night of Shiva," which is observed the night before the full moon. This night, known as "Maha Shivaratri" or "the great night of Shiva," is celebrated once a year in late winter and just before the start of summer (February or March). It is also believed to be the holy occasion when Lord Shiva got married to Goddess Parvati.

According to the North Indian Hindu calendar, this day is in the month of Phalguna, while according to the South Indian Hindu calendar, it is in the month of Magha.

Shaiva Hindus mark this night as "overcoming darkness and ignorance" in one's life and the world through Shiva, hence the celebration includes keeping a jagaran, an all-night vigil, and praying. Shiva is offered fruits, leaves, sweets, and milk. Some people also worship Shiva in tantric or Vedic ways, while others practise contemplative yoga. Shiva's Panchakshari mantra, "Om Namah Shivaya," is recited throughout the day in Shiva temples. Devotees honour Shiva by reciting the hymn known as the Shiv Chalisa. It is believed that anyone who offers the bel patra (leaves of bel plant) to Lord Shiva on this day, attains his blessings.
