Mother-in-Law Day

Mother-in-Law Day

Fourth Sunday in October
Modeled on the celebration of Mother's Day and Father's Day, Mother-in-Law's Day was first celebrated on March 5, 1934, in Amarillo, Texas, where it was initiated by the editor of the local newspaper. The observance was later moved to the fourth Sunday in October.
Mothers-in-law have never enjoyed the widespread respect and devotion that mothers have received over the years, and the rising divorce rate has given the whole concept of in-laws a less permanent place in the national imagination. This may be part of the reason why Mother-in-Law Day has failed to catch on like Mother's Day, Father's Day, and even Grandparents' Day. But many people feel that mothers-in-law deserve a special day of their own, if for no other reason than for their good humor in enduring the many jokes that have been told about them.
