## DatePicker
|
||
|
||
Use Date Picker for date input.
|
||
|
||
### Enter Date

||
|

Basic date picker measured by 'day'.
|

:::demo The measurement is determined by the `type` attribute. You can enable quick options via `shortcuts` property. The disabled date is set by `disabledDate`, which is a function.
|
||
|
||

|
||
<template>
|
||
<div class="block">
|
||
<span class="demonstration">Default</span>
|
||
<el-date-picker
|
||
v-model="value1"
|
||
type="date"
|
||
placeholder="Pick a day">
|

</el-date-picker>

return time.getTime() > Date.now()

date.setTime(date.getTime() - 3600 * 1000 * 24)

return date
|
||
})(),
|
||
}, {
|

text: 'A week ago',
|
||
value: (() => {
|

const date = new Date()

date.setTime(date.getTime() - 3600 * 1000 * 24 * 7)

### Date Range

||
|
||
Picking a date range is supported.
|
||
|
||
:::demo When in range mode, the left and right panels are linked by default. If you want the two panels to switch current months independently, you can use the `unlink-panels` attribute.

|

```
|
||
:::
|
||
|
||
### Default Value
|
||
|
||
If user hasn't picked a date, shows today's calendar by default. You can use `default-value` to set another date. Its value should be parsable by `new Date()`.
|
||
|
||
If type is `daterange`, `default-value` sets the left side calendar.

||

||

|
||
:::
|
||
|
||
### Date Formats
|
||
Use `format` to control displayed text's format in the input box.
|
||
|
||
By default, the component accepts and emits a `Date` object.
|
||
|
||
Check the list [here](https://day.js.org/docs/en/display/format#list-of-all-available-formats) of all available formats of Day.js.

### Default time for start date and end date
|
||
|
||
When picking a date range, you can assign the time part for start date and end date.
|
||
|
||
:::demo By default, the time part of start date and end date are both `00:00:00`. Setting `default-time` can change their time respectively. It accepts an array of up to two Date objects. The first string sets the time for the start date, and the second for the end date.

||
<div class="block">

||
new Date(2000, 2, 1, 23, 59, 59)
