What it is
Big Calendar lays out a month or year as a heat-tinted grid, with each day colored by your metric. It’s the dashboard equivalent of leaving a wall calendar open — instantly readable, no axis required.
What it does
Renders a full calendar grid (month or year), tints each day cell by a metric, supports tooltips, and cross-filters to the rest of the page.
Why use it
Time-of-week and time-of-year patterns jump out — the Tuesday slump, the Black Friday spike, the December lull.
Three ways teams use it
Ecommerce
Daily revenue colored across the year, holidays obvious.
Ops
Incident count per day in a year-at-a-glance heat layout.
HR
PTO calendar with team coverage at a glance.
