# Angular Scheduler Quickstart

> Render your first scheduler: the CScheduler component and an events array.

A scheduler needs the `<CScheduler>` component and an array of events. Dates
are ISO 8601 strings — with or without an explicit UTC offset:

```ts
import { Component } from '@angular/core'
import { SchedulerComponent } from '@coreui/angular-scheduler'

const pad = (n: number) => String(n).padStart(2, '0')
const day = (offset: number) => {
  const date = new Date()
  date.setDate(date.getDate() - ((date.getDay() + 6) % 7) + offset)
  return `${date.getFullYear()}-${pad(date.getMonth() + 1)}-${pad(date.getDate())}`
}

@Component({
  selector: 'docs-scheduler-day-week-example',
  imports: [SchedulerComponent],
  template: `
    <c-scheduler view="week" [dayStartHour]="8" [dayEndHour]="18" [events]="events" />
  `
})
export class SchedulerDayWeekExample {
  readonly events = [
    {
 id: 'kickoff', title: 'Kickoff', start: `${day(0)}T09:00`, end: `${day(0)}T10:00`
},
    {
 id: 'design', title: 'Design review', start: `${day(1)}T10:00`, end: `${day(1)}T11:30`, color: '#2eb85c'
},
    {
 id: 'pairing', title: 'Pairing', start: `${day(1)}T10:30`, end: `${day(1)}T12:00`
},
    {
 id: 'demo', title: 'Sprint demo', start: `${day(3)}T14:00`, end: `${day(3)}T15:00`
}
  ]
}
```

## Reacting to changes

The scheduler owns its state after mounting. Every change — drag, resize,
create, delete, repeat-rule edit — emits `eventChange` with the changed
event and a `revert` callback:

```html
<c-scheduler [events]="events" (eventChange)="onEventChange($event)" />
```

```ts
onEventChange({ action, event, revert }: EventChangePayload) {
  console.log(action, event)
  // persist to your API; call revert() if the server rejects it
}
```

See [Inputs & outputs](https://coreui.io/scheduler/angular/docs/api/options/) for the full surface.

## Time zones

Pass an IANA zone to pin the scheduler to it; otherwise the browser's zone is
used. All wall-clock math — including DST transitions — happens in that zone:

```html
<c-scheduler timeZone="Europe/Warsaw" [events]="events" />
```
