National Sons Day is an informal US day to celebrate sons and the people who raise them. Jill Nico created it in 2018, and some calendars also list a separate sons' day in late September.

About National Sons Day

The day encourages parents and other relatives to spend time with their sons, tell them what they appreciate about them, and pass on skills and values. It is often framed around being a good role model, with suggestions such as teaching a practical skill or connecting a boy with a mentor.

According to the National Day Calendar registry, Jill Nico created National Sons Day in 2018 to honor sons and those who raise them. The registry says she chose early spring because it felt like the right season, and because March 4 sounds like "march forth," which gives the date a sense of forward motion. It also notes an earlier campaign in the late 1990s by a group using the same name, which promoted a take-your-sons-to-work day as a counterpart to the daughters' version; those efforts were later combined.

The day has no official status. Some calendars list a National Sons Day on September 28 instead, but no founder is documented for that date, so March 4 is the one with a named creator. Families can mark either, or both.
