# Install and place "date-008" (Quarter Hour Slots) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/date-008.json

Registry item: https://vibeui.ru/r/date-008.json
Installs to: components/vibeui/date-008.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
Time on a quarter-hour grid: whatever is typed snaps to the nearest quarter, and the buttons move by one step.

A time field on a quarter-hour grid: buttons shift and snap, manual input rounds on blur. Zero dependencies, one file.

## 3. How to use it
import { Date008 } from "@/components/vibeui/date-008"

<Date008 label="Appointment time" defaultValue="14:30" stepMinutes={15} openAt="09:00" closeAt="20:00" />

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-date-008-* palette — do not swap it for your theme tokens
- its own light surface: the field gets shown over any background
- converting time to minutes past midnight: shifting and snapping become arithmetic instead of string surgery
- snapping on blur rather than on every keystroke: otherwise the field jumps while you are still typing
- snapping on shift: from 14:07 the button has to give 14:15, not 14:22
- disabling the buttons at the opening bounds instead of silently bumping into them
- the aria-label carrying the step size: "−15" alone reads as a bare number

## 6. You may change
- label — the field caption
- defaultValue — the starting time
- stepMinutes — the grid size, half an hour works the same
- openAt and closeAt — the opening bounds
- the accent through the accent prop

## 7. Rules
- The step attribute is in seconds: 15 minutes is 900, otherwise the browser rejects off-grid values.
- The bounds do not cross midnight: a night shift needs two intervals.
- The component knows nothing about taken slots: filter them out before submitting.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/date-008.json
https://vibeui.ru/r/date-008.json

Компонент самодостаточен: один файл, ноль зависимостей, палитра в локальных переменных --vibeui-date-008-*. Клиентский: время в состоянии, кнопки и округление меняют его. Время переводится в минуты от полуночи — так сдвиг и выравнивание по сетке становятся обычной арифметикой, без разбора строк на каждом шаге. Округление к ближайшей четверти делается по blur, а не на каждое нажатие, иначе поле начнёт прыгать во время набора. Границы приёма заданы через min и max и учитываются и кнопками, и клавиатурой.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

"use client"

import { useId, useState } from "react"
import type { ComponentPropsWithoutRef, CSSProperties } from "react"

export type Date008Props = Omit<

}

// Идея компонента: время по сетке в четверть часа. Запись «на 14:07» не нужна
// никому, но нативное поле её позволяет, поэтому любое введённое значение
// округляется до ближайшей четверти. Кнопки сдвигают время на шаг и заодно
// выравнивают по сетке: сдвиг от 14:07 даёт 14:15, а не 14:22. Границы работы
// заданы через min и max, и за них не выйдут ни кнопки, ни клавиатура.
