The Hindu calendar has 6 seasons
According to the Hindu calendar, there are 6 seasons or ‘Ritu’ in a year. Since Vedic times, the various seasons in the Indian subcontinent were classified into these six categories. While North India mostly conforms to this marked change of seasons, it is less so in South India which is mostly marked by long summers and light winters.
The six classified in the Hindu scriptures are Vasant Ritu or Spring, Grishma Ritu or Summer, Varsha Ritu or Monsoon, Sharad Ritu, or Autumn, Hemant Ritu or Pre-winter and Shishir / Shita Ritu or Winter.
