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 tone
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 as Teachers' Day since
1915. In India the birthday of the second president Sarvepalli
Radhakrishnan, 5 September, is celebrated as Teachers' Day
since 1962, while Guru Purnima has been traditionally observed as a day to
worship teachers/gurus by Hindus. Many countries celebrate their
Teachers' Day on 5 October in conjunction with World Teachers' Day, which was established by UNESCO in 1994.
