The state in the United States with the most public holidays is not explicitly listed as a single state having the most in the search results. However, several states have unique state holidays in addition to the federal holidays. For example:

• New Mexico celebrates Presidents’ Day twice (in February and the day after Thanksgiving).
• Utah has a unique holiday called Pioneer Day.
• Vermont has Town Meeting Day and Bennington Battle Day.
• Virginia celebrates Yorktown Victory Day in addition to Columbus Day.

Generally, states like New Mexico, Utah, Vermont, and Virginia have several distinct state holidays, but there is no definitive single state identified with the absolute most public holidays in the U.S. publicly available summaries at this time, with states typically observing between 6 and 11 public holidays including federal ones.

If needed, a further more detailed state-by-state count of holidays could be researched or compiled.
