year- Spring: Vasant Ritu, Summer: GrishmaRitu, Monsoon: Varsha Ritu, Autumn: Sharad
Ritu, Pre-Winter: Hemant Ritu, Winter: Shishir Ritu.
The seasons in different parts of India vary with altitude, latitude, anddistance from the sea
level; each season has its pattern of weather and has varying hours of sunlight during the
days.

Hindu calendar to structure their lives.

faithful persons still believe in this calendar, for all-importantHindu festivals and religious
occasions, each season consists of two months and six seasons.
