when is national sons day 2025

National Sons Day is celebrated twice each year in the United States — on March 4 and on September 28. In 2025, National Sons Day falls on Tuesday, March 4, and Sunday, September 28. The reason for two dates is not entirely clear, but some attribute it to social media and different groups choosing either March or September for the celebration. Both dates are recognized for honoring sons and encouraging meaningful conversations between parents and sons, started by Jill Nico in 2018.
