Set board calendar view

We need a calendar view for the product launch board so the PMs can coordinate deadlines. Set the board calendar view for the launch board, ensure due dates are visible on each card, group by month, and make the view available to the marketing and engineering teams. Confirm that cards without due dates are listed separately and tell me when it’s done.

Before I show the calendar to marketing, make it approval-friendly — surface release milestones at the top, make card owners and deadlines easy to read, and flag any cards that push work past the launch date. Add a quick legend so non-technical stakeholders understand colors and swimlanes.

I enabled the calendar view on the launch board but some cards’ due dates aren’t showing up and marketing is asking why. I’ve checked that dates exist but not why they’re hidden. Who or what is likely causing the mismatch and what should I check next so the calendar is reliable before the steering meeting?

Every quarter I spend a day recreating calendar views for multiple boards because deadlines get lost or stakeholders ask for custom filters. Which habit around how I set up due dates, card ownership, or view defaults will save me the most time and keep calendars consistent across launch, ops, and support boards?
