Teacher's Day is celebrated to honor and appreciate the hard work, dedication, and contributions of teachers in shaping the lives and futures of students. In many countries, the day is observed to recognize the role of teachers in society as mentors, guides, and role models.

### Teacher’s Day in India:

In India, Teacher's Day is celebrated on **September 5th** every year to mark the birth anniversary of **Dr. Sarvepalli Radhakrishnan**, a philosopher, scholar, and the second President of India. When Dr. Radhakrishnan became the President, some of his students and friends approached him to celebrate his birthday. He, however, requested that instead of celebrating his birthday, the day should be dedicated to all teachers. Thus, since 1962, his birthday has been celebrated as Teacher's Day in India.

### Significance:

1. **Appreciation**: It is a day for students to show their gratitude and respect to teachers for their invaluable role in guiding them academically and personally.

2. **Mentorship**: Teachers play a pivotal role not just in imparting education but in shaping the character, future, and moral values of students.

3. **Nation-building**: Teachers are often regarded as the backbone of society, helping to build the intellectual and moral fabric of a nation by nurturing the minds of future leaders.

### Celebrations:

- Students often organize special events, cultural programs, and activities to honor their teachers.

- Gifts, cards, and tokens of appreciation are given to teachers by students.

- In schools and colleges, the roles of teachers and students may be reversed, with students taking classes to show their understanding and respect for their educators' hard work.

Internationally, **World Teacher's Day** is celebrated on **October 5th**, as designated by UNESCO to highlight the global importance of teachers and quality education.
