National Family PJ Day is observed in the USA every year on November 14, celebrating the joy of lounging in pajamas with loved ones. This holiday encourages families to engage in cozy activities such as pajama parties, movie or game nights, and sleepovers, often featuring matching pajamas as a fun tradition. The day was launched in 2019 by the apparel company Soma to promote comfortable sleepwear ahead of the holiday season. Pajamas, which originated in the Indian subcontinent and became popular in Western Europe during the Victorian Era, have evolved into various styles suitable for both nightwear and loungewear. The trend of matching family pajamas gained significant popularity in the 1950s and was revived by social media, particularly after the viral "XMAS Jammies" video in 2013. Families are encouraged to share their pajama moments on social media using the hashtag #NationalFamilyPJDay.
