# 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

|
||
|
|
|

import { maxTime } from 'date-fns'
|
||
|
|
|
||
|
|
const isValid = 8640000000000001 <= maxTime
|
||
|
|
//=> false
|
||
|
|
|
||
|
|
new Date(8640000000000001)
|
||
|
|
//=> Invalid Date
|

```
|
||
|

|
import { minTime } from 'date-fns'
|
||
|
|
|
||
|
|
const isValid = -8640000000000001 >= minTime
|
||
|
|
//=> false
|
||
|
|
|
||
|
|
