HOW BECOMES DAY AND NIGHT IN WORLD...

Do you know..?
      You know that the length of day and night is not always equal. This happens because of earths inclined axis and its Revolution the sun.
      In the northern hemisphere, between 22 march and 23 September, the days are longer than the nights. Therefore it is warmer there. That is, it is summer in the northern hemisphere. However, during this same period in the southern hemisphere, the nights are longer than days. The earth gets less heat in these parts and therefore it is winter in the southern hemisphere.
           In the period from 23 September to 22 march, the days are longer than the nights in the southern hemisphere. It gets more heat and it is summer their. In this period in the northern hemisphere, it is nights that are longer. The northern hemisphere gets less heat and it is winter there.
          Note that there may difference in these dates due to the leap year.
           In India, summer, they rainy season and winter the considered to be the main season. We also divide the year into six seasons, namely, vasant, grishma, varsha, sharad, hemant, and shishir.
      The cycle of six seasons is called the 'rituchakra'. Many of our festival are connected with the seasons. Many of our songs and games are also related to the different seasons...
