Calendar
The Calendar by ChartPad is a custom Power BI visual for reading date-based data the way people actually think about time — as days, weeks and months on a grid. Every row of your data becomes an event placed on the dates it covers, so bookings, deadlines, absences, campaigns, shifts and releases can be scanned at a glance, coloured by category, and clicked to cross-filter the rest of the report.
It is built for report editors who want a proper calendar inside Power BI — six views, public holidays, working hours, cross-filtering and 40+ interface languages — without leaving the report or writing any code.
What it can do
- Six views — Month, Week, Day, List, Quarter and Year, switched from the visual's own header and turned on or off per report.
- Single-day and multi-day events — plot a start date on its own, or a start and end date that draws a bar spanning every day it covers.
- Timed and all-day events — datetime columns produce placed events on the Week and Day timelines; date-only columns produce all-day bars.
- Categories and colours — colour events by a category field, with a per-category colour picker and an interactive legend.
- Density handling — cap how many events a day cell shows and collapse the rest into a "+N more" chip with an expandable panel.
- Public holidays — built-in national holiday calendars for ten countries, shown as inert background events in your own colour.
- Working hours — mark working days and business hours; non-working hours are shaded on the Week and Day timelines.
- Today and now — today's date is circled in every view, and a live "now" line is drawn on the Week and Day timelines.
- Cross-filtering — click an event (or a legend item) to filter the rest of the report; ctrl+click to multi-select.
- Details on demand — a details popover on click, Power BI tooltips on hover (including report-page tooltips), and a Detail URL field that opens a record in another system.
- International — dates, times, weekday names and the 12/24-hour clock follow the viewer's Power BI language, with right-to-left support.
- Accessible — keyboard-reachable events and controls, screen-reader labels, and full Power BI high-contrast support.
The Calendar is a Microsoft-certified Power BI visual: its code has been reviewed and tested to confirm it doesn't access any external services, so your data never leaves Power BI. Certified visuals are safe for enterprise use and support export to PowerPoint/PDF and email subscriptions. See Certified by Microsoft.
Anatomy of the visual
| Region | What it shows |
|---|---|
| Header | The Today button, the view selector, the previous/next arrows, and the period title (e.g. March 2026, Q1 2026, 2026). |
| Weekday row | Day-of-week labels, starting on the first day of week you choose. |
| Day cells | One cell per day, with the day number and the events that fall on it. Days outside the current month are dimmed. |
| Events | One chip or bar per row of data, coloured by category. |
| Overflow chip | A "+N more" button when a day holds more events than the cell is allowed to show. |
| Legend | Optional list of categories, positionable on any side, and clickable to filter. |
How to read it
- An event's position is the day (and, in Week/Day view, the time) it occupies.
- A bar spanning several cells is a multi-day event, running from its start date to its end date.
- A squared-off edge on a bar means the event continues into the previous or next week.
- An event's colour is its category — matching the legend.
- A circled day number is today.
- A shaded band on the Week or Day timeline is outside working hours.
- A "+N more" chip means the day holds more events than the cell shows; click it to see the rest.
Before you start
The Calendar is free to try — every feature works during evaluation. To use it in a published report without an on-visual license notice, each editor and viewer needs a license (a 30-day free trial is available). See Licensing & support.
