Vaisakhi, also known as Baisakhi, marks the first day of the month of Vaisakh and is traditionally celebrated annually on 13 April and sometimes 14 April.
It is seen as a spring harvest celebration primarily in Punjab and Northern India.
Whilst it is culturally significant as a festival of harvest, in many parts of India, Vaisakhi is also the date for the Indian Solar New Year.

The Nishan Sahib in Sikhism is a triangular flag made of cotton or silk cloth, with a tassel at its end. The current form of the Nishan Sahib that is in use throughout Gurdwaras around the world has an orange (saffron) background color that has the Khanda symbol in the center of the flag. It is commonly hoisted on a tall flagpole outside Gurdwaras.
