Week Planner

Weekly schedule with time blocks: a typical week with optional odd and even weeks, or a dated week the user edits.

c2-week-planner shows a week: seven day columns on an hour scale, each event a block from its start to its end time. By default it is a typical week, with no dates: an event names the weekday it happens on and repeats every week, or, with alternate-weeks, only in odd or even weeks (weeks: "odd"), as school and shared-custody schedules do. Set date to show a real calendar week with week-by-week navigation instead, and editable to let the user add, move and resize events. Today’s column is tinted (--c2-week-planner__day__today--background, drawn inside the grid lines) and carries a line at the current time. Overlapping events cascade, each stepped in from the one before and drawn over it, so the earlier one’s title stays readable, and the hour range (start-hour, end-hour, 8 to 18 by default) grows to fit every event.

Import

import '@c2n/components/week-planner'

The examples use icons from the separate @c2n/feather-icons package: npm install @c2n/feather-icons.

Usage

Add event
Click an empty spot, drag a block, or drag its bottom edge.

Events

Each entry is { id?, title, day?, date?, start, end, weeks?, color?, textColor? }: day is mon to sun and repeats every week, date (YYYY-MM-DD) is a single day shown only in a dated week, and start and end are 24-hour HH:MM times (24:00 ends at midnight). An entry needs a day or a date; date wins when it has both. Entries whose times are invalid or end before they start are skipped. color is any CSS colour for that block (its text stays white in both themes; add textColor for a light color); otherwise --c2-week-planner__event--background applies.

Heading

heading puts a title at the start of the header (--c2-week-planner__title--font-size, --c2-week-planner__title--font-weight) and becomes the planner’s accessible name, unless aria-label is set. It is called heading rather than title because title is the browser’s tooltip attribute, which would hover over the whole planner.

For more than plain text, put your own markup in the heading slot: an icon next to the name, a link, or a field that renames the planner. It replaces the heading text inside the same h2, and names the planner unless heading or aria-label is set.

<c2-week-planner aria-label="Team week">
  <c2-text-field slot="heading" value="Team week" aria-label="Planner name"></c2-text-field>
</c2-week-planner>

Actions

The actions slot puts controls of your own at the end of the header, e.g. an “Add event” button or a settings menu, spaced by --c2-week-planner__actions--gap. They sit before the previous/next day arrows on a narrow planner, and the header shows for them even without a heading or the week switch. The planner leaves what they do to you.

<c2-week-planner heading="Team week">
  <c2-button class="planner-add" slot="actions"><c2-feather-plus slot="prefix-icon"></c2-feather-plus>Add event</c2-button>
  <c2-icon-button class="planner-icon-action" slot="actions" tooltip="Settings" aria-label="Settings"><c2-feather-settings></c2-feather-settings></c2-icon-button>
</c2-week-planner>

Odd and even weeks

Alternate weeks are off by default: every entry shows each week and weeks is ignored. Add the alternate-weeks attribute to turn them on. weeks is then "all" (the default), "odd" or "even", counted by ISO week number, where week 1 holds the year’s first Thursday, and an Odd week | Even week switch appears above the grid: a segmented c2-button-group, styled through its own --c2-button-group__* variables set on the planner. It opens on the kind of the current week, whose button carries the current ISO week number in a c2-badge, and every-week entries appear in both. Set parity="odd" or parity="even" to choose the view yourself; the switch fires parity-change with the kind now shown. Today’s column is only marked while the switch shows the current kind of week.

Blocks are buttons: clicking one, or pressing Enter on it, fires event-click with the entry in event.detail.event.

Dated weeks

Set date to any day (YYYY-MM-DD) to show the calendar week holding it, starting on week-start or the language’s first day. The day headers then carry the day of the month (--c2-week-planner__day-number--font-weight), the header shows the week’s range (--c2-week-planner__week-title--color, --c2-week-planner__week-title--font-size) and previous week / next week arrows with a Today button, and today’s column is only marked in the week that holds it. The navigation updates date and fires week-change with the first and last day shown, { start, end } as YYYY-MM-DD — the moment to load that week’s entries. It does not bubble: listen on the planner itself.

Entries with a date show in their own week only; entries with a day keep repeating every week, so a dated plan can mix one-off appointments with a routine. With alternate-weeks, weeks follows the ISO number of the week shown and there is no switch. Without date the planner stays the dateless typical week, and entries with a date are left out of it.

Editing

editable lets the user arrange the plan. The planner never changes events itself: it reports what the user asked for, and you update events.

  • Add. Clicking an empty spot fires slot-click with { day, date?, start, end }: the time under the pointer, snapped down to snap-minutes (30 by default), and an hour-long range, capped at 24:00. The hour under the pointer is tinted (--c2-week-planner__slot__hover--background). From the keyboard, each day column starts with a “New event” button, invisible until it has focus, at the column’s first free hour; Enter fires the same event.
  • Move and resize. Drag a block to another time or day, or drag its bottom edge (--c2-week-planner__resize-handle--height) to change its end. A dashed preview (--c2-week-planner__preview--*) shows where it lands while the block itself fades (--c2-week-planner__event__dragging--opacity); Escape cancels. The drop fires event-change with { event, changes }: event is the entry from events and changes its new start, end and, for a day entry, day, or, for a date entry, date, so spreading changes onto the entry applies it. A press that does not travel a few pixels is still a click (event-click).
  • Keyboard. On a focused block, Alt+Arrow Up/Down moves it by snap-minutes, Alt+Arrow Left/Right by a day (a day entry wraps around the week), and Alt+Shift+Arrow Up/Down changes its end; each fires event-change, and the block keeps focus once you have applied it.
import '@c2n/components/week-planner'
import type { WeekPlannerEvent } from '@c2n/components/week-planner'

const planner = document.querySelector('c2-week-planner')!
planner.date = '2026-10-07'
planner.editable = true

// loadWeek: your own fetch of that week's entries.
planner.addEventListener('week-change', ({ detail }) => loadWeek(detail.start, detail.end))
planner.addEventListener('slot-click', ({ detail }) => {
  const entry: WeekPlannerEvent = { id: crypto.randomUUID(), title: 'New task', date: detail.date, start: detail.start, end: detail.end }
  planner.events = [...planner.events, entry]
})
planner.addEventListener('event-change', ({ detail }) => {
  planner.events = planner.events.map((entry) => (entry === detail.event ? { ...entry, ...detail.changes } : entry))
})

Narrow screens

Below 640px of width the planner shows three days, and below 420px a single day, of a strip that scrolls sideways and snaps to a day: swipe it on a touch screen, or page through the week with the previous/next arrows that appear in its header. It opens on today and the hour labels stay in place. The breakpoints follow the planner’s own width, not the viewport’s, so a planner in a narrow sidebar switches too.

In a layout that sizes it from its content, such as a centred flex column, the planner takes 720px or the space available, whichever is smaller; give it a width to choose another.

Language

The planner’s text follows locale (fr, en-GB, …) and, when it is not set, the browser’s language. The day columns start on that language’s usual first day (Sunday in en-US, Monday in fr or en-GB, Saturday in ar-EG); week-start (monday, sunday or saturday) overrides it. Day names, “today” and “this week” come from the browser’s Intl data, so they exist in every language; the switch labels (Odd week, Even week) and the accessible names are built in for English, French, German, Spanish, Italian, Portuguese, Dutch and Vietnamese, and fall back to English otherwise. A dated week formats its dates and range through Intl too.
