@Calhistorian here's a pretty basic implementation. It will ask for a month/day and defaults to the current date if input is left blank. Could probably be adapted to grab the date from the page title if in a daily note. Hasn't been tested for every possible edge case, but generally seems to work.

• 42SmartBlock Get Week

  • <%NOBLOCKOUTPUT%><%SET:date,<%INPUT:Enter month and day%>%>
  • <%JAVASCRIPT:javascript Date.prototype.getWeek = function() { var onejan = new Date(this.getFullYear(), 0, 1); return Math.ceil((((this - onejan) / 86400000) + onejan.getDay() + 1) / 7); } let date = roam42.smartBlocks.activeWorkflow.vars.date return new Date(date ? date : new Date()).getWeek()%>

Slightly different example

- #42SmartBlock Get ISO Week Number Date
    - <%JAVASCRIPT:```javascript
Date.prototype.getWeekNumber = function(){
  var d = new Date(Date.UTC(this.getFullYear(), this.getMonth(), this.getDate()));
  var dayNum = d.getUTCDay() || 7;
  d.setUTCDate(d.getUTCDate() + 4 - dayNum);
  var yearStart = new Date(Date.UTC(d.getUTCFullYear(),0,1));
  return Math.ceil((((d - yearStart) / 86400000) + 1)/7)
};

let date = roam42.smartBlocks.activeWorkflow.vars.date 
let weekNumber = new Date(date ? date : new Date()).getWeekNumber()
let year = new Date(date ? date : new Date()).getFullYear()
return "[[" + year + "-W" + weekNumber + "]]"```%>

Humm, I could be wrong but this is actually implemented now, using ww as format

Example: <%DATE:This week,ww%>
