# Constants
|
|
|
|
date-fns provides with a number of useful constants.
|
|
|
|
## Usage
|
|
|
|
The constants could be imported from `date-fns/constants` or directly
|
|
from `date-fns`:
|
|
|
|
```js
|
|
import { maxTime } from 'date-fns/constants'
|
|
import { minTime } from 'date-fns'
|
|
|
|
function isAllowedTime(time) {
|
|
return time <= maxTime && time >= minTime
|
|
}
|
|
```
|
|
|
|
## Constants
|
|
|
|
### `maxTime`
|
|
|
|
Maximum allowed time:
|
|
|
|
```js
|
|
import { maxTime } from 'date-fns'
|
|
|
|
const isValid = 8640000000000001 <= maxTime
|
|
//=> false
|
|
|
|
new Date(8640000000000001)
|
|
//=> Invalid Date
|
|
```
|
|
|
|
### `minTime`
|
|
|
|
Minimum allowed time:
|
|
|
|
```js
|
|
import { minTime } from 'date-fns'
|
|
|
|
const isValid = -8640000000000001 >= minTime
|
|
//=> false
|
|
|
|
new Date(-8640000000000001)
|
|
//=> Invalid Date
|
|
```
