Celebrated In: India
Teacher's day is not just a day for fun and change of roles. It is also a day to remember how much of hard work and time goes in, before a teacher walks into that classroom and teaches you that chapter. It is a day for showing gratitude towards the person who has patiently heard you out when you asked the same question a hundred times. It is also a day to thank the person who guided you in matters more than academic. A person like that truly deserves a special day earmarked to him/her, right? So, the next September 5th, make sure you pick up that phone or make an extra effort to call your teacher and thank him/her for the lighthouse they have been in your life.
Now that's what an awesome teacher does; I guess. They teach us, guide us, love us, scold us, cry when we pass out and then never forget us. The Indian scriptures also speak about the four entities that make us what we are. Mata, Pita, Guru and Devam (Mother, Father, Teacher and God). A stature of a teacher comes before God Himself. I am sure this is why Dr. Sarvepalli Radhakrishnan, the first Vice-President and the second President of India (for his passion for education) insisted on celebrating his birthday as the Indian Teacher's day and thus arrived September 5th. The first teacher's day being in 1962, we have came a long way celebrating and being grateful to all those people who have taught us not just academics but values and ways of life as well.
World Teachers' Day is a global observance and not a public holiday.
It is considered a "celebration" day, where teachers and students report to school as usual but the usual activities and classes are replaced by activities of celebration, thanks and remembrance. At some schools on this day, the responsibility of teaching is taken up by the senior students to show appreciation for their teachers.
Another day set aside for commemorating teachers in India and Nepal is Guru Purnima, also called 'Ashad sukla purnima'. It typically falls in mid-July.
In United Nation Teachers Day is celebrated on 5th of October.
