In Sikhism, Vaisakhi is one of the most significant days and it commemorates the establishment of the Khalsa at Anandpur Sahib in 1699, by the 10th Sikh Guru, Guru Gobind Singh Ji.
Vaisakhi falls in the Nanakshai Calendar on the first day of Vaisakh month. Vaisakhi is determined by the Solar Calendar and usually falls on April 14.
The festival bears a great significance for the Sikhs due of the fact that on the Vaisakhi Day in the year 1699, the 10th Guru of the Sikhs, Guru Gobind Singh laid down the foundation of the Panth Khalsa, that is the Order of the Pure Ones. This day is also observed as the thanksgiving day by the farmers whereby the farmers pay their tribute, thanking God for the abundant harvest and also praying for the future prosperity. Vaisakhi is one of the important festivals celebrated with fun and fervor by people of other religions too. It is also used as a celebration for those accepting the five Ks.
