Payments are non-refundable. See our Terms of service.

Builds an activity calendar (heatmap) of the last 12 months into your own project: three stat tiles (days practised, longest streak, current streak) above a calendar of 53 week columns by 7 day rows; each day is a rounded square shaded from pale sand (none) to deep ocean blue (an hour); month names above, Mon, Wed and Fri at the side, a Less to More key below; arrow keys walk the days. Plain HTML, CSS and JavaScript, or matched to React, Next.js, Vue, Svelte, Astro or Tailwind when the project uses them. Comes with a working reference and a check that screenshots it at phone, tablet and desktop widths and flags sideways overflow, text under 12px, missing alt text and names, low contrast, no focus styles, motion that ignores reduced motion, leftover sample words and emoji icons. Use when an app tracks a daily habit or activity (practice, workouts, writing, commits, sales) and wants to show a year of it, or someone asks for a calendar heatmap, streak calendar or activity grid.

About this skill

You say

Add a calendar heatmap of daily workouts to our running app's profile page. Details in brief.md, the data is runs.csv.

It said back

I added the running calendar as a standalone profile page. There was no existing app in the folder, so I used plain HTML, CSS and JavaScript. I couldn't integrate it into your real profile page.

I ran the skill's check at 390, 768 and 1440px before my last edit. All checks passed: no sideways overflow, no text under 12px, contrast, focus styles, reduced motion, no leftover sample words and no emoji icons. I didn't re-run it after reducing the grid height from 190px to 172px, so that last tweak is unchecked.
