Invisible Day – July 4, 2024

Invisible Day is celebrated each year on July 4 in the United States. On some days don’t you feel like disappearing? There are days when we feel left out or invisible, while there are also days we want to feel that way. Invisible Day makes us wonder what we would do if we were invisible — would you eavesdrop on other people’s conversations or make your way around town without being seen by anyone? Would you use your power of invisibility for the greater good or will you be selfish about it? Invisible Day presents us with so many interesting possibilities!

History of Invisible Day

Who knows how Invisible Day came to be? Whatever be the reason and whoever is the brain behind it, probably wanted us to focus on those days when we feel tired or defeated. On some days we simply don’t feel our best, and all we desire is to leave everything behind and simply vanish into thin air. But if you want to disappear on Invisible Day, you can do so by taking leave from work and spending the day doing what pleases you. You can also go away on a short holiday and disconnect from the world for a while.

Invisible Day is also an acknowledgment of mental health issues. The celebrations understand that it’s okay to feel down every once in a while In a world where we are constantly connected to work and family, hyperconnectivity also makes us feel lonely. People also feel anxious when they are required to constantly be in touch with others. Invisible Day is an encouragement to take time off your schedule and have some alone time.

When we hear ‘invisible,’ we know that humans cannot actually become invisible. However, the closest experience of invisibility that we can have is with invisible ink. Invisible ink, also known as security ink or sympathetic ink, when used for writing does not let the text appear on paper. It can later be made visible by some other means.
