Copy# Mint — Date Picker Specs
 
## Component
- name: date-picker
- file: composition pattern — no standalone registry file
- installs to: composed inline from components/ui/popover, components/ui/calendar, components/ui/button
- dependencies: date-fns, lucide-react, react-day-picker
- registryDependencies: popover, calendar, button
 
## What is it
A trigger button that opens a floating calendar popover for selecting single dates, date ranges, or presets. The button doubles as the value display, showing the formatted date or a placeholder when empty. Use it whenever a date must be picked from a calendar view; prefer a plain text input only when users need to type arbitrary dates quickly.
 
## Visual identity
The trigger uses the outline Button variant — transparent background with a soft green-tinted border — giving it a form-field feel. The popover surfaces on --popover (white/dark surface) with no padding, letting the Calendar fill it edge-to-edge. Selected days use the medium-green --primary fill, creating a fresh, confident contrast anchor within the Mint palette.
 
## Design tokens
--muted-foreground: oklch(0.52 0.06 155) / oklch(0.6 0.06 155)   — placeholder text when no date selected
--primary: oklch(0.5 0.14 155) / oklch(0.62 0.15 155)             — selected day fill
--primary-foreground: oklch(1 0 0) / oklch(0.1 0 0)  — selected day text
--accent: oklch(0.92 0.05 155) / oklch(0.26 0.05 155)               — today highlight and range middle background
--accent-foreground: oklch(0.32 0.1 155) / oklch(0.88 0.06 155)   — today text
--popover: oklch(1 0 0) / oklch(0.269 0 0)                 — calendar popover surface
--popover-foreground: oklch(0.145 0 0) / oklch(0.985 0 0)  — calendar text
--border: oklch(0.88 0.04 155 / 60%) / oklch(0.32 0.05 155 / 40%)            — trigger button border
--ring: oklch(0.5 0.14 155) / oklch(0.62 0.15 155)                — focus ring on trigger and day buttons
 
## External dependencies
- date-fns: date formatting (format, addDays) and locale support
- react-day-picker: DayPicker engine powering Calendar — provides mode, selected, onSelect, disabled, numberOfMonths, autoFocus props
 
## States
- empty trigger: text-muted-foreground placeholder ("Pick a date") when no date is selected
- populated trigger: formatted date string replaces placeholder; full foreground colour
- focus: 3px ring in --ring colour on the trigger button and on individual day buttons (focus-within on day cell)
- selected day: bg-primary, text-primary-foreground; persists on hover
- today: bg-accent, text-accent-foreground (unselected)
- range middle: aria-selected:bg-accent, aria-selected:text-accent-foreground
- range start / end: rounded-l-md / rounded-r-md with bg-primary treatment
- outside days: opacity-50, text-muted-foreground
- disabled days: opacity-50, text-muted-foreground, not interactive
- nav arrows: opacity-50 by default, hover:opacity-100
 
## Conventions
- Always wrap the trigger Button in PopoverTrigger asChild to avoid an extra DOM node
- Always set PopoverContent className="w-auto p-0" align="start" — w-auto lets the calendar set its own width; p-0 is required for the edge-to-edge calendar layout
- Always add autoFocus to Calendar so keyboard focus moves into the calendar on open
- Always add CalendarIcon to the trigger button (mr-2 size-4 before the label, or ml-auto size-4 opacity-50 for form-field style)
- Use cn() on the trigger className to conditionally apply text-muted-foreground when the value is undefined or null
- For controlled open state (presets, close-on-select), manage open + onOpenChange on Popover and call setOpen(false) after selection
- Range mode: use DateRange { from?: Date; to?: Date } as state; set numberOfMonths={2} for two-month view; render "from – to" with a fallback to just "from" when to is undefined
- Preset buttons: render inside PopoverContent above or beside the calendar; use addDays(new Date(), n) for relative offsets; always close the popover after a preset is applied
- In React Hook Form: use FormField + FormControl with field.value as selected and field.onChange as onSelect; pass a disabled predicate to Calendar to enforce valid date ranges
- Format tokens: "PPP" → "June 29th, 2026"; "LLL dd, y" → "Jun 29, 2026" — pick one format per product context and keep it consistent
