National Introvert Day 2025. World introvert day was first introduced in 2019 by a group of introverted activists who wanted to create a space where introverts could feel seen, heard, and celebrated. World introvert day is an opportunity to break stereotypes like introverts are often mistaken as being aloof or disengaged.

This is easy to do on social media, so friends will understand that you want to be alone. World introvert day is recognized as a day to understand the many introverts around the world better — the one holiday best celebrated, not by throwing a party, but by canceling one.
