Teachers are the real holder of knowledge, enlightenment and prosperity using which they nourish and prepare us for our life. They serve as source of lighting lamp in our lives. It is our teachers who stand behind our success. Out teachers too have lots of daily routine problems just like us and our parents but they always keep their teaching profession at top and attend schools or colleges to complete their job responsibilities. Nobody say them thanks for their priceless job. So, we as students have some responsibility towards our teachers at least we can say them thanks once a year.

Teacher’s day is celebrated every year on 5th of September to pay honour to our selfless teachers and their priceless job. 5th of September is a birth anniversary of our earlier President Dr. Sarvapalli Radhakrishnan who had requested to celebrate his birthday as the teachers day to respect teachers all over India. He was great fond of the teaching profession. Our teachers shape us to be academically wonderful and morally good by enhancing our knowledge, skill and confidence level. They always promote us to do every impossible thing possible to do better in the life. Teacher’s day is celebrated with great joy and enthusiasm by the students. They say give them lots of greeting orally or through greeting cards. :)
