The Sikhs celebrate everyday when they do the ardas; however on vaisakhi we mark the occasion with festivities; families go to gurdwara's together; we rejoice in the name of freedom we have been blessed with through the actions of the Tenth Guru "Guru Gobind Singh Ji" .
Vaisakhi commerotes the day when; The tenth guru gathered his followers at a time when Sikhs and hindhu's were being persecuted by Muslim Emporers of the the Mogul Dynasty. He asked his followers if they were willing to give up life for the guru and his teachings his beliefs in the Sikh way of life. 5 volunteers came forward and were baptised as Amritdhari Sikhs.
The Guru himself was baptised and asked his followers to stand proud and be recognised, even if this meant certain torture and death in the hands of the Muslim rulers.
It is the sheer courage and determination of these few who against the masses ensured the survival of the Sikhs and some say the Hindu's in India. As if it had not been for the might of the Sikh Army at that time; it can be argued India would have been converted to an Islamic state by force.
