There is no major U.S. federal holiday on the very next Monday, but there are several smaller observances that day, depending on the exact date and where you live.

Since today is Thursday, March 5, 2026, the “Monday coming up” is March 9, 2026. That specific Monday is not a U.S. federal holiday like Memorial Day or Labor Day, so banks and government offices will generally be open. However, the following day, Tuesday March 10, 2026, has a long list of fun and niche observances often mentioned on “what holiday is today” sites, such as International Bagpipe Day, Mario Day (“MAR10”), International Day of Awesomeness, National Women and Girls HIV/AIDS Awareness Day, and National Ranch Dressing Day, among others.

Because “what holiday is Monday coming up” is also a trending-style query online, a lot of recent news articles answering it are actually about the next federal holiday in general (for example, pieces explaining that Columbus Day/Indigenous Peoples’ Day is the Monday federal holiday in October). Those pieces don’t refer to this specific March Monday, but to the broader federal- holiday calendar.

If you tell me your country or state, I can narrow it down to any local or school holidays that might fall on that Monday.
