DayPicker v10 is out

[gpbl]

I have finally released DayPicker v10. This is a cleanup major release that removes APIs deprecated since v9 and makes the public API more consistent across props, CSS classes, and styles.

It also introduces the new @daypicker/react package name and moves non-Gregorian calendars into standalone @daypicker/* packages, so apps can install only the calendar code they need.

You can read the full changelog and the updated upgrading guide.

Notable changes

• Deprecated APIs from v9 have been removed.
• @daypicker/react is now the preferred package name for new projects.
  • Non-Gregorian calendars are now published as smaller standalone packages, such as @daypicker/hijri, @daypicker/buddhist, @daypicker/hebrew, @daypicker/ethiopic, and @daypicker/persian.

shadcn/ui compatibility

shadcn/ui uses DayPicker for its Calendar component, which is something I really appreciate, but their current implementation still depends on some deprecated DayPicker CSS APIs that were removed in v10.

I opened a PR to update their component, but it has not received much attention so far. Until that is merged, upgrading DayPicker directly inside a shadcn/ui Calendar component may require some manual changes.

I also decided not to change the default navigation layout in v10, even though it would fix this long-standing accessibility issue. If you are affected by that issue, you can opt in today with:

<DayPicker navLayout="after" />

Scoped packages

One of the biggest changes in v10 is the new scoped package name: @daypicker/react.

The existing react-day-picker package is still available in v10 for compatibility, but new projects should prefer:

npm install @daypicker/react

This new @daypicker/* scope gives DayPicker more room to evolve. For example, non-Gregorian calendars no longer need to live inside the main React package, so apps only install the calendar code and dependencies they actually use.

It also gives us a cleaner path for future work, such as the proposed Temporal package.

Reporting issues

If you run into problems while upgrading to v10, please open an issue or discussion with a small reproduction when possible.

Useful details include:

• the DayPicker package and version you are using;
• whether you import from react-day-picker or @daypicker/react;
• whether you use shadcn/ui or another wrapper component;
• the relevant DayPicker props, class names, or custom components involved.

Thanks to everyone who tested v9, reported deprecated API issues, and helped make this cleanup possible!
