Anand Karaj...

Anand Karaj (Punjabi: ਅਨੰਦ ਕਾਰਜ, anand kāraj) is the Sikh marriage ceremony, meaning "Blissful Union" or "Joyful Union", that was introduced by Guru Amar Das. The four Lavan (marriage hymns which take place during the marriage ceremony) were composed by his successor, Guru Ram Das. It was originally legalised in India through the passage of the Anand Marriage Act 1909 but is now governed by the Sikh Reht Maryada (Sikh code of conduct and conventions) that was issued by the Shiromani Gurdwara Prabandhak Committee (SGPC).
In a recent verdict of the Sri Akaal Takht Sahib,i.e. a Hukumnama, Anand Karaj can only take place in a Gurudwara. This has raised some controversy, as it seems the only real reason for this is to protect the financial welfare of the Gurudwara. Any Amritdhari (Baptized) sikh may perform the marriage ceremony.

Pakistan passed the Sikh Anand Marriage Act in 2007. A Sikh from anywhere in the world can register his or her marriage there, though the marriage ceremony has to be conducted in the country as it extends the provisions of the law applicable to any Sikh irrespective of his nationality. There had been instances when Sikhs from various countries had got their marriages registered in Pakistan...
The Anand Karaj ceremony is joyous and festive event in which families and friends from both sides are heavily involved. Most Sikh weddings take place in the morning and are completed before noon. Following the ceremony is a langar or a formal lunch. The wedding event can last for the whole day and may spill into the next day.
Most families combine the wedding ceremony with the engagement ceremony called the "Kurmai", where the Kurmai is held just before the wedding vows or Laava. The engagement ceremony can also be held as a separate event on a different day. It is usually conducted in the Gurdwara or at the home of the Groom-to-be. It involves Ardas, Kirtan, "Sagaan" (Exchange of gifts) and Langar. In the "Sagaan" ceremony, the groom is presented with a kara, kirpan, Indian sweets, fresh fruits, dried fruits and nuts. The bride-to-be's family in turn are presented with garments and sweets for the Bride-to-be.
