Relating to the office hours of an election authority during an election period.

HB 640 clarifies that during election periods, election authorities (like county or city offices) must be open on "regular business days" - defined as days when their main office is typically open for business. The bill specifically notes that for independent school districts, this means the school district's main business office hours apply. It directly affects election offices and voters needing access to these locations during voting periods. The change takes effect September 1, 2025, and does not alter existing voting procedures or requirements.
