National Grandparents Day honors grandparents and the bond between generations. In the United States it falls on the first Sunday after Labor Day each September; other countries observe similar days for grandparents at different points in the year.

The observance is largely credited to Marian McQuade, a West Virginia housewife who campaigned through the 1970s to establish a day honoring grandparents and to encourage young people to seek out the wisdom of the elderly, including those in nursing homes. President Jimmy Carter signed a proclamation establishing the national observance in 1978, with the first celebration held in 1979.

Common traditions include family visits and gatherings, phone calls, sharing photos or memories, and sending a card or a heartfelt Wishes message.

Beyond family celebration, the day was originally meant to raise awareness of isolated elderly people and strengthen ties between generations. Many people express their appreciation with a warm Quotes post dedicated to their grandparents.
