Usage

DayView displays events for a single day with time slots.

All day
08:00
09:00
10:00
11:00
12:00
13:00
14:00
15:00
16:00
17:00
import dayjs from 'dayjs';
import { useState } from 'react';
import { DayView } from '@mantine/schedule';
import { events } from './data';

function Demo() {
  const [date, setDate] = useState(dayjs().format('YYYY-MM-DD'));

  return (
    <DayView
      date={date}
      onDateChange={setDate}
      events={events}
      startTime="08:00:00"
      endTime="18:00:00"
    />
  );
}

Time range

Use startTime and endTime props to set the visible time range. Times should be in HH:mm:ss format.

All day
09:00
10:00
11:00
12:00
13:00
14:00
15:00
16:00
import { DayView } from '@mantine/schedule';
import { events } from './data';

function Demo() {
  return (
    <DayView
      date={new Date()}
      events={events}
      startTime="09:00:00"
      endTime="17:00:00"
    />
  );
}

Start scroll time

Use startScrollTime prop to set the initial scroll position, for example to open the view at the start of business hours instead of midnight. The value must be in HH:mm:ss format.

All day
00:00
01:00

21:00
22:00
23:00
import { useState } from 'react';
import { DayView, ScheduleEventData } from '@mantine/schedule';
import { events as initialEvents } from './data';

function Demo() {
  const [events, setEvents] = useState(initialEvents);

  const handleEventDrop = ({ eventId, newStart, newEnd }: { eventId: string | number; newStart: string; newEnd: string }) => {
    setEvents((prev) =>
      prev.map((event) =>
        event.id === eventId ? { ...event, start: newStart, end: newEnd } : event
      )
    );
  };

  return (
    <DayView
      date={new Date()}
      events={events}
      startScrollTime="09:00:00"
      scrollAreaProps={{ mah: 500 }}
      withEventsDragAndDrop
      onEventDrop={handleEventDrop}
    />
  );
}

Interval minutes

intervalMinutes prop controls the granularity of time slots. Default is 15 minutes.

All day
08:00
09:00
10:00
11:00
12:00
13:00
14:00
15:00
16:00
17:00
import { DayView } from '@mantine/schedule';
import { events } from './data';

function Demo() {
  return (
    <DayView
      date={new Date()}
      events={events}
      startTime="08:00:00"
      endTime="18:00:00"
      intervalMinutes={30}
    />
  );
}

Slot label interval

By default, the time column shows one label per hour. Set slotLabelInterval prop to display labels more often, for example every 15 or 30 minutes. The value must be a multiple of intervalMinutes, other values are rounded up to the next valid one. Increase slotHeight so that the labels have enough space:

function Demo() {
  return (
    <DayView

      events={events}
      startTime="08:00:00"
      endTime="18:00:00"
      intervalMinutes={15}
      slotLabelInterval={15}
      slotHeight={160}
    />
  );
}

Sub-hour grid lines

When intervalMinutes is smaller than 60, set withSubHourGridLines={false} to display only one grid line per hour. Events are still created and resized with the smaller interval.

import { useState } from 'react';
import dayjs from 'dayjs';
import { DayView, ScheduleEventData } from '@mantine/schedule';

const today = dayjs().format('YYYY-MM-DD');

const initialEvents: ScheduleEventData[] = [
  {
    id: 1,
    title: 'Morning Standup',
    start: `${today} 09:00:00`,
    end: `${today} 09:30:00`,
    color: 'blue',
  },
  {
    id: 2,
    title: 'Team Meeting',
    start: `${today} 11:15:00`,
    end: `${today} 12:00:00`,
    color: 'green',
  },
  {
    id: 3,
    title: 'Code Review',
    start: `${today} 14:00:00`,
    end: `${today} 14:45:00`,
    color: 'violet',
  },
];

function Demo() {
  const [events, setEvents] = useState(initialEvents);

  const handleEventResize = ({ eventId, newStart, newEnd }: { eventId: string | number; newStart: string; newEnd: string }) => {
    setEvents((prev) =>
      prev.map((event) =>
        event.id === eventId ? { ...event, start: newStart, end: newEnd } : event
      )
    );
  };

  // Events snap to 15 minutes increments, but only one grid line per hour is displayed
  return (
    <DayView
      date={new Date()}
      events={events}
      startTime="08:00:00"
      endTime="18:00:00"
      intervalMinutes={15}
      withSubHourGridLines={false}
      withEventResize
      onEventResize={handleEventResize}
    />
  );
}

All-day events

Events that span the entire day are displayed in a dedicated all-day section at the top. When there are more than 2 all-day events, the component shows a "+N more" indicator.

All day
08:00
09:00
10:00
11:00
12:00
13:00
14:00
15:00
16:00
17:00
import { DayView } from '@mantine/schedule';
import { events } from './data';

function Demo() {
  return (
    <DayView
      date={new Date()}
      events={events}
      startTime="08:00:00"
      endTime="18:00:00"
    />
  );
}

Overlapping events

When multiple events overlap in time, they are automatically positioned side by side with appropriate widths and offsets.

All day
08:00
09:00
10:00
11:00
12:00
13:00

function Demo() {
  return (
    <DayView
      date={new Date()}
      events={events}
      startTime="08:00:00"
      endTime="18:00:00"
    />
  );
}

Current time indicator

Set withCurrentTimeIndicator to display a line showing the current time. By default, it's only shown for the current day. Set withCurrentTimeBubble={false} to hide the time bubble.

All day
00:00
01:00

      date={new Date()}
      events={events}
      withCurrentTimeIndicator
      withCurrentTimeBubble
    />
  );
}

Current time indicator in a different timezone

@mantine/schedule does not perform timezone conversions. By default, the current time indicator is positioned based on the user's local time.

To display the indicator in a different timezone, use getCurrentTime prop – a function that returns the current time. In the example below, the current time is converted to the selected timezone with the dayjs timezone plugin:

import timezone from 'dayjs/plugin/timezone';
import utc from 'dayjs/plugin/utc';
import { Select, Stack } from '@mantine/core';
import { DayView } from '@mantine/schedule';
import { getEvents } from './data';

dayjs.extend(utc);
dayjs.extend(timezone);

const timezones = ['UTC', 'America/New_York', 'Europe/Berlin', 'Asia/Kolkata', 'Asia/Tokyo'];

function Demo() {
  const [tz, setTz] = useState('UTC');

  // getCurrentTime is called on every tick, so the indicator keeps updating
  const getCurrentTime = () => dayjs().tz(tz).format('YYYY-MM-DD HH:mm:ss');
  const currentDate = getCurrentTime().split(' ')[0];

  return (
    <Stack>
      <Select
        label="Display timezone"
        data={timezones}
        value={tz}
        onChange={(value) => setTz(value!)}
        allowDeselect={false}
      />

      <DayView
        date={currentDate}
        events={getEvents(currentDate)}
        getCurrentTime={getCurrentTime}
        startScrollTime={dayjs(getCurrentTime()).subtract(2, 'hour').format('HH:mm:ss')}
        withCurrentTimeIndicator
        withCurrentTimeBubble
      />
    </Stack>
  );
}

Business hours

Use highlightBusinessHours and businessHours props to visually distinguish business hours from non-business hours. The businessHours prop accepts a tuple with start and end times in HH:mm:ss or HH:mm format.

All day

function Demo() {
  return (
    <DayView
      date={new Date()}
      events={events}
      highlightBusinessHours
      businessHours={['09:00:00', '17:00:00']}
    />
  );
}

Business hours do not need to align with the slot grid. When a boundary falls inside a slot, the slot and the time label next to it are painted up to the exact minute:

      events={events}
      highlightBusinessHours
      businessHours={['07:42', '19:01']}
    />
  );
}

Business hours colors

Set --day-view-business-hours-bg and --day-view-non-business-hours-bg CSS variables with vars prop or in CSS to change the colors. Both variables apply to time slots and time labels:

import { DayView } from '@mantine/schedule';
import { events } from './data';

function Demo() {
  return (
    <DayView
      date={new Date()}
      events={events}
      highlightBusinessHours
      businessHours={['07:42', '19:01']}
      vars={() => ({
        dayView: {
          '--day-view-business-hours-bg': 'var(--mantine-color-yellow-light)',
          '--day-view-non-business-hours-bg': 'var(--mantine-color-blue-light)',
        },
      })}
    />
  );
}

Custom time slot props

Use getTimeSlotProps to add props to individual time slots, for example data-business-hours or event handlers. The function receives { start, end } datetime strings in YYYY-MM-DD HH:mm:ss format and returns an object of props or undefined. Event handlers returned by the function do not override internal handlers, both are called.

      startScrollTime="07:00:00"
      getTimeSlotProps={({ start }) => {
        const hour = parseInt(start.split(' ')[1], 10);
        if (hour >= 7 && hour < 20) {
          return { 'data-business-hours': true };
        }
        return { 'data-non-business-hours': true };
      }}
    />
  );
}

Slot height

Customize the height of time slots and the all-day section using slotHeight and allDaySlotHeight props. The slotHeight represents the height of a 1-hour slot.

  );
}

Custom header

You can build a custom header using ScheduleHeader compound components combined with your own controls. Set withHeader={false} on the view and compose the header externally.

        withHeader={false}
      />
    </div>
  );
}

Header format

Use headerFormat prop to customize the date format in the header. The format uses dayjs format syntax or can be a function that returns a formatted string.

      startTime="08:00:00"
      endTime="18:00:00"
      headerFormat="dddd, MMMM D"
    />
  );
}

Slot label format

slotLabelFormat prop controls the format of time labels. It accepts a dayjs format string or a function that returns a formatted string.

      startTime="08:00:00"
      endTime="18:00:00"
      slotLabelFormat="h:mm A"
    />
  );
}

Radius

Use radius prop to change the border radius of the view and events.

      startTime="08:00:00"
      endTime="18:00:00"
      radius={0}
    />
  );
}

Overlap mode

eventOverlapMode prop controls how overlapping events share the horizontal space:

  • columns (default) – the width is split evenly between overlapping events. Every event is fully visible, but gets narrower as more events overlap.
  • cascade – each event is indented from the previous one and drawn on top of it. Events keep a readable width, but cover the events underneath. Use it when many events overlap at the same time.

import { DayView, ScheduleEventOverlapMode } from '@mantine/schedule';
import { events } from './data';

function Demo() {
  const [mode, setMode] = useState<ScheduleEventOverlapMode>('cascade');

  return (
    <Stack>
      <SegmentedControl
        value={mode}
        onChange={(value) => setMode(value as ScheduleEventOverlapMode)}
        data={[
          { value: 'columns', label: 'columns' },
          { value: 'cascade', label: 'cascade' },
        ]}
      />

      <DayView

        endTime="14:00:00"
        eventOverlapMode={mode}
      />
    </Stack>
  );
}

In cascade mode, a covered event is raised above the others when it is hovered or focused. Use eventOverlapRaiseDelay prop to change the hover delay in milliseconds, 600 by default:

import { DayView } from '@mantine/schedule';

function Demo() {
  return <DayView date={new Date()} eventOverlapMode="cascade" eventOverlapRaiseDelay={250} />;
}

Drag and drop

Enable drag and drop by setting withEventsDragAndDrop prop. Use onEventDrop callback to handle event drops. All-day events cannot be dragged.

To reject a drop based on where the event lands – for example to prevent double booking – use preventEventOverlap and canDropEvent, see drop validation.

];

function Demo() {
  const [events, setEvents] = useState(initialEvents);

  const handleEventDrop = ({ eventId, newStart, newEnd }: { eventId: string | number; newStart: string; newEnd: string }) => {
    setEvents((prev) =>
      prev.map((event) =>
        event.id === eventId ? { ...event, start: newStart, end: newEnd } : event

  );
}

Drag interval

By default events snap to intervalMinutes when moved by drag and drop. Set eventDragInterval to use a different snap step for dragging – for example, a grid with 30-minute slots whose events can be moved in 15-minute increments. A ghost preview shows where the event will land:

External drag and drop

Use onExternalEventDrop to allow dragging items from outside the component into the schedule. External items must set data in dataTransfer during their onDragStart. The callback receives the DataTransfer object and the drop target datetime.

Bidirectional drag and drop

Combine onExternalEventDrop with withEventsDragAndDrop to drag items both into and out of the schedule. When an event is dragged, the schedule sets application/json data with { eventId } in dataTransfer. Read it in your drop zone to identify the event.

Custom event rendering

Use renderEventBody prop to customize how events are displayed. This allows you to add custom icons, badges, or any other content to events.

Full event customization

Use renderEvent prop to fully customize event rendering. The function receives the event as the first argument and the props of the event root element (including children) as the second argument. Use it to wrap events in HoverCard, Tooltip or other components.

  );
}

Background events

Set display="background" on an event to render it as a full-width, semi-transparent block behind regular events. By default it cannot be clicked, dragged, or resized. Background events are useful for marking unavailability, lunch breaks, focus time, or other blocked periods.

      startTime="08:00:00"
      endTime="18:00:00"
      intervalMinutes={30}
    />
  );
}

Interactive background events

Set withInteractiveBackgroundEvents prop to make background events clickable. onEventClick is called with the background event, use event.display === 'background' to tell it apart from regular events.

An interactive background event covers the time slots underneath it: clicks and drag-to-select in its range go to the event. Interactive background events still cannot be dragged.

Last clicked: nothing yet

Resizable background events

Set withEventResize together with withInteractiveBackgroundEvents to make background events resizable. onEventResize is called with the background event, the same way as for regular events.

All-day background events are never resizable. To keep background events fixed while regular events stay resizable, return false from canResizeEvent:

<DayView
  withEventResize
  withInteractiveBackgroundEvents
  canResizeEvent={(event) => event.display !== 'background'}
/>

Create and update events

Set withDragSlotSelect prop to allow users to drag across time slots to select a time range. When the drag ends, onSlotDragEnd is called with the range start and end dates. Combine it with onTimeSlotClick, onAllDaySlotClick and onEventClick to create and edit events.

Responsive styles

DayView uses @container queries for responsive styles. The component automatically adjusts its layout based on the container width, hiding labels and reducing padding on smaller screens. Container queries are supported in all modern browsers.

Accessibility

Focus management

Only the first time slot is included in the tab order. All other time slots can be reached with arrow keys.

Keyboard interactions

KeyDescription
ArrowDownFocuses next time slot
ArrowUpFocuses previous time slot

Slot labels

Each time slot button has an aria-label attribute with the time range (e.g., "Time slot 08:00:00 - 09:00:00").
