Generally, no. RCW 42.30.070, which is the Open Public Meetings Act (OPMA) provision that requires the schedule for regular meetings to be set by ordinance, resolution, or bylaw, states that: “If at any time any regular meeting falls on a holiday, such regular meeting shall be held on the next business day.”
If the governing body decided to hold that meeting on a different date besides the next business day, they could either cancel the regular meeting and reschedule it as a special meeting pursuant to RCW 42.30.080, or adjourn the regular meeting to the later time following the procedures at RCW 42.30.090.
Here is a blog post that explains the process for either adjourning (i.e., rescheduling) or canceling a public meeting, Best Laid Plans: Following the OPMA When Adjourning or Canceling a Public Meeting (2023). And here is a blog on special meetings, Special Meetings: Answering Some Frequently Asked Questions (2024).
