World Teacher’s Day commemorates a global document - first adopted in 1996 - which sets out the rights and responsibilities of teachers.
Google has celebrated the day with a Doodle which features a spectacle-wearing multitasking octopus in front of a blackboard.
World Teachers' Day, which falls on 5 October every year, aims to focus on “appreciating, assessing and improving the educators of the world”.
The theme this year is “Young Teachers: The Future of the Profession” and organisers are drawing attention to the need to think about ways to draw “the brightest minds and young talents in the profession”.
And countries across the world choose to celebrate their own educators in a wide range of ways on various dates throughout the year.
