Teachers’ Day is a special day for the appreciation of teachers, and may include celebrations to honor them for their special contributions in a particular field area, or the community in general.
The idea of celebrating Teachers’ Day took root in many countries during the 19th century; in most cases, they celebrate a local educator or an important milestone in education.
This is the primary reason why countries celebrate this day on different dates, unlike many other International Days. For example, Argentina has commemorated Domingo Faustino Sarmiento’s death on 11 September) since 1915.
In India Guru Purnima is traditionally observed as a day to venerate teachers, the birthday of the second president Sarvepalli Radhakrishnan (5 September) is also celebrated as Teacher’s Day since 1962.
Many countries celebrate World Teachers’ Day, established by UNESCO in 1994, on 5 October as their Teacher’s Day.
