Selecting March 29, 2026 picks the next day in DatePicker (reproducible on demo site)

[scottwilson24]

Current behaviour

Selecting March 29, 2026 in the DatePicker selects March 30, 2026 instead.

Clicking/tapping March 29 results in the following day being selected.

This is reproducible on the official demo site and is not limited to a specific locale.

---

Expected behaviour

Selecting March 29, 2026 should select March 29, 2026.

---

How to reproduce?

1. Open the official demo site: https://www.reactnativepaperdates.com/
2. Open the "Single Date" picker
3. Navigate to March 2026
4. Select March 29
5. Observe that March 30 is selected instead
6. Repeat with different locales

---

What have you tried so far?

• Tested across multiple locales on the demo site
• Tested with and without a controlled date prop in app code
• Removed min/max date constraints
• Normalised dates to avoid timezone/DST handling issues
• Confirmed the issue occurs on the official demo site (not app-specific)

---

Additional context

This date corresponds to the UK daylight saving time (DST) transition (clocks moving forward), which suggests a possible issue with date handling around DST boundaries.

@scottwilson24 I created a PR, give a try and let me know.

@iM-GeeKy I tested this locally and can confirm it fixes the issue.

Selecting March 29, 2026 (Europe/London) now correctly selects March 29 instead of March 30.

Thanks for the fix 👍

Great! I think I need to get @RichardLindhout to tweak the release task in the pipeline, so we'll release it as soon as that's fixed. If you need the fix immediately you can always patch it.
