README badges
Live SVG badges for GitHub READMEs, wikis, and status pages. No key, no script, no tracking; one image URL that stays current. Dates are UTC, day-level.
Next holiday
Which holiday is coming and how soon. Handy at the top of internal tools and on-call docs.

The number sprint planning and billing runs actually care about.
[](https://dierum.io/?utm_source=badge&utm_campaign=business-days-left)Trading day today
Green on trading days, red with the reason when the market is closed. Day-level, not market hours.

The next stretch of three or more days off. The morale badge.

Any of the 250+ region codes from the reference works in the URL, including subdivisions (US-CA, DE-BY) and markets (XNYS). Badges cache for six hours. If you need the underlying numbers rather than a picture, that is the API. Curious which country's calendar gives the most long weekends next year? See the 2027 rankings.
