# Segmented date input

> Day, month and year boxes that jump ahead on their own, change with the arrow keys and flip a small calendar page.

## Where to use it

A date field split into three numeric boxes, the way desktop operating systems do it. Typing moves on by itself, the slash key skips ahead and the up and down arrows roll each value. A tear-off calendar page shows the weekday, the week number appears below, and impossible dates such as 31 February shake the field.

Change the main color to match the active box and the page header. It fits booking forms, delivery dates and birthdays where a full calendar popup is too heavy, and it keeps the mobile number keyboard on every box.

## Code

### HTML

```html
<div class="uvq06-dt"><span class="lb" id="uvq06-dt-l">Arrival date</span><div class="fd" role="group" aria-labelledby="uvq06-dt-l"><div class="pg" aria-hidden="true"><span class="wd"></span><span class="dn"></span></div><input class="sg" data-min="1" data-max="31" maxlength="2" inputmode="numeric" autocomplete="off" aria-label="Day" placeholder="DD"><span class="sp" aria-hidden="true">/</span><input class="sg" data-min="1" data-max="12" maxlength="2" inputmode="numeric" autocomplete="off" aria-label="Month" placeholder="MM"><span class="sp" aria-hidden="true">/</span><input class="sg y" data-min="1900" data-max="2099" maxlength="4" inputmode="numeric" autocomplete="off" aria-label="Year" placeholder="YYYY"></div><p class="ft" aria-live="polite"><span class="wn"></span><span class="wk">Week <b></b></span></p></div>

## Prompt for AI assistants

Paste this into ChatGPT, Claude, Cursor, v0 or Lovable to adapt the block to your stack (Tailwind, Vue, Svelte…):

````text
I want to add the “Segmented date input” block (Inputs) from AIMRAN Library to my project.

## What it is
Day, month and year boxes that jump ahead on their own, change with the arrow keys and flip a small calendar page.

## Chosen settings
- Main color: #ea580c
- Secondary color: #ffedd5
- Size: 16px (from 12 to 24px)
- Speed: 1x (from 0.5 to 2x)
- Text: "Fecha de llegada"

## What I need
1. Add it to my project with the same look and animation as the reference code: same sizes, colours, radii, shadows, timings and easing.
2. It is built with plain HTML and CSS (the reference wraps it in a React component with its CSS). If my project uses something else (Vue, Svelte, Astro, plain HTML…), translate it without losing any behaviour. If I use Tailwind, turn the styles into classes; if not, keep the CSS in its own file.
3. Expose the settings above as props (or CSS variables) with those values as defaults.
4. Make it work well on phones: nothing that depends only on hover, touch targets of at least 44 px and no overflow on 320 px screens.
5. Make it look right in light and dark mode.
6. Keep it accessible: semantic HTML, roles and aria-* where needed, visible focus and keyboard support.
7. Respect prefers-reduced-motion: with reduced motion, no big animations but the same end result.
