Shiv Jayanti, also known as Shivaji Maharaj festival, is a festival and public holiday of the Indian state of Maharashtra. This festival is celebrated on February 19, the birth anniversary of [[Shivaji Maharaj], the first Chhatrapati of the Marathas. He established Hindavi Swarajya (Hindavī Svarājya; "Self-Rule of the hindavi people"). Some people celebrate this day as per Hindu Calendar in Maharashtra.^[1][2]

Shivaji I was born at the Shivneri fort on the third day of the Krishna Paksha of the Phalgun month in the year 1551 of the Shalivahan Shaka.^[3] In the Gregorian calendar, the date generally occurs between February and March.

As per the Julian calendar, the date is accepted to be February 19, 1630. However, many Hindus celebrate Shiv Jayanti as per the Hindu calendar.^[4]

The Marathi Shalivahana Hindu calendar birthdate of Shivaji is Falgun Krishna paksha 3, 1551^[5] Julian February 19, 1630, in Shivneri Fort. The error of not converting the Julian date to the corresponding Gregorian one is still not corrected.^[6]
