Schedule

This is a living schedule and subject to change

Code

function generateDay(day){
  // deconstruct the date so it doesn't think it is in UTC
  const [year, month, date] = day.date.split('-').map(Number);
  const d = new Date(year, month-1, date);

  const messages = day.entries.map(e=>htl.html`<li>${md2html(e)}</li>`);
  const reading = day.reading.length > 0 ? htl.html`<li>📚 ${md2html(day.reading.join(", "))}</li>` : '';
  const assigned = day.assigned.map(e=>htl.html`<li><strong>Assigned</strong> ${md2html(e)}</li>`);
  const due = day.due.map(e=>htl.html`<li><strong>Due</strong> ${md2html(e.link)}</li>`);

  return htl.html`<li class="entry">${label} <ul>${messages} ${reading} ${assigned} ${due}</ul></li>`;
}


function generateWeek(week, number){
  const undatedItems = week.undated.map(entry=>htl.html`<li>${md2html(entry)}</li>`);
  const days = week.days.filter(d=>d.entries.length + d.due.length + d.assigned.length > 0);
  const dayItems = days.map(d=>generateDay(d));

  return htl.html` <div class="weekBlock">
