International Pineapple Day is observed worldwide every June 27, celebrating the delicious and versatile fruit, the pineapple. The holiday originated in 2011 as International Bring Your Pineapple to Work Day, created by Andrew Lee and James Tamplin, co-founders of the app development platform Firebase. It gained popularity when a colleague brought a pineapple to work the following year, leading to its annual celebration. People honor the day by enjoying fresh or canned pineapples, cooking dishes that include pineapples, drinking pineapple juice or piña coladas, and hosting pineapple-themed parties. The holiday has garnered attention from major brands, celebrities, and influencers, making it a widely recognized occasion for pineapple lovers.
