Put a Pillow on your Fridge Day is celebrated annually on May 29th, originating from a tradition where people would place a piece of cloth in their larder for good luck prior to the advent of refrigeration. This quirky holiday encourages participants to continue the practice by either putting a pillow on their fridge or placing a piece of linen from their bedroom inside it. The day has gained popularity on social media, with users sharing creative images of pillows in fridges and even designing custom pillowcases for the occasion. While the original custom aimed to attract prosperity and ensure plentiful food, the celebration has evolved to embrace a humorous and lighthearted spirit. The tradition serves as a reminder of past food storage practices and the importance of appreciating food, which many take for granted today.
