Grandparents' Day is a secular holiday celebrated worldwide to honor the bond between grandparents and their grandchildren, with its first recorded celebration taking place in Poland in 1965. The date varies significantly by country—for instance, Japan has observed it as a national holiday since 1966 (third Monday of September), while Canada officially recognized it in 1995 (second Sunday of September). In 2021, Pope Francis established a global World Day for Grandparents and the Elderly on the fourth Sunday of July, offering a plenary indulgence to participants. Some celebrations have unique origins, such as France's holiday launched by a coffee brand in 1987, or Malta's official day (since 2014) created by advocate Philip Michael Chircop. The holiday serves to strengthen intergenerational bonds and express gratitude, with some countries like the Netherlands even promoting the "adoption" of a grandparent for the day. Ultimately, it is a global recognition of grandparents' vital role in family structure and child upbringing.
