               1.  Sub Topic- The Seasons (The Cold and The Hot weather season) (pg 31-32)


               The India Meteorological Department (IMD) describes four different seasons and
               the Lunisolar Hindu calendar describes six different types of seasons in India throughout the
               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.
               Since the Vedic period, peoples across India and South Asia have been using this Lunisolar
               Hindu calendar to structure their lives.
               These ancient Indian calendars are used in India, Bangladesh, Nepal, and Sri Lanka; some
               faithful persons still believe in this calendar, for all-importantHindu festivals and religious
               occasions, each season consists of two months and six seasons.
