**The current version of this package supports Angular 20**

If you need support for other Angular version, see _Breaking Changes_ below.

## Breaking Changes

-   Version 20.x.x is the official release for Angular 20 and it also supports Angular 19.
-   Version 19.x.x >= no longer supports ng 18. If you need ng 18 support, stick with version 18.x.x.
-   Version 18.x.x >= no longer supports ng 17. If you need ng 17 support, stick with version 17.x.x.
-   Version 17.x.x >= no longer supports ng 16 - 13. If you need ng 16-13 support, stick with version 16.x.x.
-   Version 14.x.x >= no longer supports < ng 13. If you need View Engine support, stick with version 13.x.x.
-   Version 13.1.0+ no longer supports the `MomentJs` time adapter natively. If you want to use the MomentJs adapter, see [GitHub](https://github.com/danielmoncada/date-time-picker-moment-adapter) or [npm](https://www.npmjs.com/package/@oengus/angular-datetime-picker-moment-adapter).
-   If you need ng 8 support, please stick with: https://github.com/DanielYKPan/date-time-picker

## Description

Simple Angular date time picker. Online doc is [here](https://daniel-projects.firebaseapp.com/owlng/date-time-picker), Online demos(StackBlitz) are [here](https://stackblitz.com/edit/angular-vvp849) and [here](https://stackblitz.com/edit/angular-i7ykf5).
This picker is responsive design, so feel free to try it in your desktops, tablets and mobile devices.

## How to Use

1.  Install with [npm](https://www.npmjs.com): `npm install @oengus/angular-datetime-picker --save`
2.  Add styles.
    If you are using Angular CLI, you can add this to your styles.css:
    ```css
    @import '@oengus/angular-datetime-picker/assets/style/picker.min.css';
    ```
    If you are not using the Angular CLI, you can include the picker.min.css via a `<link>` element in your index.html.
3.  Add **OwlDateTimeModule** and **OwlNativeDateTimeModule** to your **@NgModule** like example below

    ```typescript
    import { NgModule } from '@angular/core';
    import { BrowserModule } from '@angular/platform-browser';
    import { MyTestApp } from './my-test-app';
    import { OwlDateTimeModule, OwlNativeDateTimeModule } from '@oengus/angular-datetime-picker';

    @NgModule({
        imports: [BrowserModule, OwlDateTimeModule, OwlNativeDateTimeModule],
        declarations: [MyTestApp],
        bootstrap: [MyTestApp],
    })
    export class MyTestAppModule {}
    ```

4.  Connecting a picker to an input and a trigger.
    ```html
    <input [owlDateTime]="dt1" [owlDateTimeTrigger]="dt1" placeholder="Date Time" /> <owl-date-time #dt1></owl-date-time>
    ```
    ```html
    <input [owlDateTime]="dt2" placeholder="Date Time" />
    <span [owlDateTimeTrigger]="dt2"><i class="fa fa-calendar"></i></span>
    <owl-date-time #dt2></owl-date-time>
    ```
    The examples above are quite basic. The picker has much more features,
    and you could learn more about those from [demo page](https://danielykpan.github.io/date-time-picker/).

## Choose a date implementation

The date-time picker was built to be date implementation agnostic.
Developers need to make sure to provide the appropriate pieces for the picker to work with their chosen implementation.
There are two pre-made modules, users need to import one of them or build your own one (learn more about this from [here](https://danielykpan.github.io/date-time-picker/#locale-formats)).

-   `OwlNativeDateTimeModule` - support for native JavaScript Date object
-   `OwlUnixTimestampDateTimeModule` - support for milliseconds since Epoch (number)

##### Date/Time Adapter Extensions
