MI HB6409

Designates the first Monday after the National Football League's Super Bowl championship game as a public holiday in Michigan for purposes of banking, financial instruments, and court proceedings.

Reorganizes the existing list of state holidays (New Year's Day, MLK Jr. Day, Lincoln's Birthday, Washington's Birthday, Memorial Day, Independence Day, Labor Day, Columbus Day, Veterans Day, Christmas Day, and Thanksgiving Day) into a numbered subsection format.

Maintains Saturday afternoons (12 noon to 12 midnight) as half holidays and clarifies that banks and financial institutions are not required to remain open during this time unless they choose to do so.

Allows bills of exchange, bank checks, and promissory notes that would be due on any listed holiday to be presented for payment on the next business day instead.

Updates statutory language throughout by replacing "shall" with "does" or "must" for modern drafting consistency.
