Kalyana Vratam is one of the eight auspicious vratas. When the Sun is shining in the Pisces sign(mIna rAsi) that is in the month of paN^guni (mid of March to mid of April) on the uththara naxaththiram on the Moons growing face (shukla paxam), this vratam is observed. This is the day Shakthi married Lord Shiva after a great austerity in the Himaalayas, as the daughter of Himavaan. It is also observed as the auspicious day when Lord Muruga married devaseenaa.

This vratam is explained in the skandha purANam. In the morning after getting up, the observer of the vratam should meditate on the charming Lord shiva in the wedding posture with umA. After taking bath and through with other required deeds, should worship the Lord. The golden idol of the God and Goddess ( who can afford to) should be anointed devotionally with holy substances. Then decorating them should make the wedding ceremony of the Goddess with the God. Making the nice and sweet offerings to the divine Parents, should salute them. Inviting the spiritual people who think of good to all the creatures, who have learnt the vEdas and who are devotees of Lord shiva, along with their wives, should host them a feast. Later should go to the shiva temple, worship, circumambulate three times and prostrate in front of the Lord. In the night should dine along with the kind hearted devotees of Lord shiva and eat the sweet dishes like fruits and pAyasam. Should sleep on the dharbai grass. The next morning after regular deeds, should donate the golden idol of God and Goddess to disciplined love hearted people who are the devotees of Lord shiva. Should eat only once that day.
