Establishing trick-or-treat day.

SB 5159 designates the last Saturday in October (or the last Friday if weather requires) as "Trick-or-Treat Day" for recognition in Washington state. It adds this date to the list of recognized days in state law (RCW 1.16.050), alongside other observances like Juneteenth and Native American Heritage Day. The bill does not create a legal holiday or alter school calendars - it simply formally acknowledges this date for community celebration. The legislature states this aims to reduce school absences and improve safety by shifting trick-or-treating to earlier in the day before dark. This is a procedural recognition, not a policy change affecting voting or funding.
