Pongal is a harvest festival equivalent to a thanksgiving event celebrated by Tamils across the world. Pongal in Tamil means "boiling over or spill over." The act of boiling over of milk in the clay pot is considered to denote future prosperity for the family.

Traditionally celebrated at harvest time, it is a celebration of the prosperity associated with the harvest by thanking the rain, sun and the farm animals that have helped in the harvest. In villages, new clothes are worn and people owning cows find this festival important. Pongal is celebrated by the Indian state of Tamil Nadu as well as Tamils worldwide, including those in Sri Lanka, Malaysia, Mauritius, South Africa, USA, Canada and Singapore. The festival is at least 1000 years old although some believe that the festival is more than 2000 years old.

Vaisakhi (vaisakhi, also known as Baisakhi) is an ancient harvest festival in Punjab, which also marks beginning of a new solar year, and new harvest season. Vaisakhi also has religious significance for Sikhs. It falls on the first day of the Vaisakh month in the solar Nanakshahi calendar, which corresponds to April 13 or April 14 in the Gregorian calendar.

Vaisakhi is one of the most significant holidays in Sikh calendar, commemorating the establishment of the Khalsa in 1699. Vaisakhi is celebrated by the Khalsa as their birthday every year, the day corresponding to the event when they were created by Guru Gobind Singh in 1699.

The festival is celebrated as Rongali Bihu in Assam, Naba Barsha in Bengal, Puthandu in Tamil Nadu, Vishu (or Vaishakhi) in Kerala, and the Sinhalese/Tamil new year festival in Sri Lanka. Besides Punjab, Vaisakhi is widely celebrated as traditional harvest festival in many northern states of India, such as Haryana, Himachal Pradesh and Uttaranchal.

Ganesha Chaturthi or Ganesha Festival is a day on which Lord Ganesha, the son of Shiva and Parvati, is believed to bestow his presence on earth for all his devotees. It is also known as Vinayaka Chaturthi or Vinayaka Chavithi in Sanskrit, Kannada, Tamil and Telugu, Chavath in Konkani and as Chathaa in Nepal Bhasa. It is celebrated as it is the birthday of Lord Ganesha. The festival is observed in the Hindu calendar month of Bhaadrapada, starting on the shukla chaturthi (fourth day of the waxing moon period). Typically, the day falls sometime between 20 August and 15 September. The festival lasts for 10 days, ending on Ananta Chaturdashi. This festival is observed in the lunar month of bhadrapada shukla paksha chathurthi madhyahana vyapini purvaviddha. if chaturthi prevails on both days, the first day should be taken. Even if chaturthi prevails for complete duration of madhyahana on the second day, but if it prevails on previous day's madhyahana period even for one ghatika (24 minutes) the previous day should be taken. (Ref. Dharmasindhu and Indian Calendric System, by Commodore S.K. Chatterjee (Retd). Madhyahana is the 3rd / 5th part of the day (Sunrise-sunset).

Ganesha, the elephant-headed son of Shiva and Parvati, is widely worshipped as the supreme god of wisdom, prosperity and good fortune.

While celebrated all over India, it is most elaborate in Maharashtra, Goa (Biggest festival for Konkani people all over the world) Gujarat, Karnataka and Andhra Pradesh, and other areas which were former states of the Maratha Empire. Outside India, it is celebrated by Newars in Nepal and Tamil Hindus in Sri Lanka.

Raksha Bandhan (the bond of protection in Hindi) is a Hindu festival, which celebrates the relationship between brothers and sisters. It is celebrated on the full moon of the month of Shraavana.

The festival is marked by the tying of a rakhi, or holy thread by the sister on the wrist of her brother. The elder brother in return offers a gift to his sister and vows to look after her same as elder sister return offers to younger brother. The brother and sister traditionally feed each other sweets. It is not necessary that the rakhi can be given only to a brother by birth; any male can be "adopted" as a brother by tying a rakhi on the person, that is "blood brothers and sisters", whether they are cousins or a good friend. Indian history is replete with women asking for protection, through rakhi, from men who were neither their brothers, nor Hindus themselves. Rani Karnavati of Chittor sent a rakhi to the Mughal Emperor Humayun when she was threatened by Bahadur Shah of Gujarat. Humayun abandoned an ongoing military campaign to ride to her rescue.

The rakhi may also be tied on other special occasions to show solidarity and kinship (not necessarily only among brothers and sisters), as was done during the Indian independence movement.
