National Grandparents Day takes place on September 10, 2023. National Grandparent's Day is a secular holiday celebrated in the United States since 1978 and officially recognized in a number of countries on various days of the year, either as one holiday or sometimes as a separate Grandmothers Day and Grandfathers Day.
National Grandparents Day in the U.S. is the first Sunday after Labor Day, in September. The holiday is expected to grow in significance over the next decade and beyond as the number of grandparents in the United States rises from 65 million in 2011 to 80 million in 2020 as a result of the baby boom. Grandparents in America are also increasingly responsible for child care and support. (With material from: Wikipedia)
