# secondsInMonth

> Determine the number of seconds in a month.

<section class="usage">

## Usage

```javascript
var secondsInMonth = require( '@stdlib/time/seconds-in-month' );
```

#### secondsInMonth( \[month\[, year]] )

Returns the number of seconds in a month.

```javascript
var num = secondsInMonth();
// returns <number>
```

By default, the function returns the number of seconds in the current month of the current year (according to local time). To determine the number of seconds for a particular month and year, provide `month` and `year` arguments.

```javascript
var num = secondsInMonth( 2 );
// returns <number>

num = secondsInMonth( 2, 2016 );
// returns 2505600

num = secondsInMonth( 2, 2017 );
// returns 2419200
```

A `month` may be either a month's integer value, three letter abbreviation, or full name (case insensitive).

```javascript
var num = secondsInMonth( 2, 2016 );
// returns 2505600

num = secondsInMonth( 'feb', 2016 );
// returns 2505600

num = secondsInMonth( 'february', 2016 );
// returns 2505600
```

The function also supports providing a [`Date`][date-object] object.

```javascript
var num = secondsInMonth( new Date() );
// returns <number>
```
