# minutesInMonth
|
|
|
|
> Determine the number of minutes in a month.
|
|
|
|
<section class="usage">
|
|
|
|
## Usage
|
|
|
|
```javascript
|
|
var minutesInMonth = require( '@stdlib/time/minutes-in-month' );
|
|
```
|
|
|
|
#### minutesInMonth( \[month\[, year]] )
|
|
|
|
Returns the number of minutes in a month.
|
|
|
|
```javascript
|
|
var num = minutesInMonth();
|
|
// returns <number>
|
|
```
|
|
|
|
By default, the function returns the number of minutes in the current month of the current year (according to local time). To determine the number of minutes for a particular month and year, provide `month` and `year` arguments.
|
|
|
|
```javascript
|
|
var num = minutesInMonth( 2 );
|
|
// returns <number>
|
|
|
|
num = minutesInMonth( 2, 2016 );
|
|
// returns 41760
|
|
|
|
num = minutesInMonth( 2, 2017 );
|
|
// returns 40320
|
|
```
|
|
|
|
A `month` may be either a month's integer value, three letter abbreviation, or full name (case insensitive).
|
|
|
|
```javascript
|
|
var num = minutesInMonth( 2, 2016 );
|
|
// returns 41760
|
|
|
|
num = minutesInMonth( 'feb', 2016 );
|
|
// returns 41760
|
|
|
|
num = minutesInMonth( 'february', 2016 );
|
|
// returns 41760
|
|
```
|
|
|
|
The function also supports providing a [`Date`][date-object] object.
|
|
|
|
```javascript
|
|
var num = minutesInMonth( new Date() );
|
|
// returns <number>
|
|
```

## Notes
|
|
|
|
- The function's return value is a generalization and does **not** take into account inaccuracies due to daylight savings conventions, crossing timezones, or other complications with time and dates.
