# quarterOfYear
> Determine the quarter of the year.
## Usage

var quarterOfYear = require( '@stdlib/time/quarter-of-year' );
```
#### quarterOfYear( \[month] )
Returns the quarter of the year.
```javascript
var q = quarterOfYear();
// returns
```
By default, the function returns the quarter of the year for the current month in the current year (according to local time). To determine the quarter for a particular month, provide either a month or a [`Date`][date-object] object.
```javascript
var q = quarterOfYear( new Date() );
// returns
q = quarterOfYear( 4 );
// returns 2
```
A `month` may be either a month's integer value, three letter abbreviation, or full name (case insensitive).
```javascript
var q = quarterOfYear( 4 );
// returns 2
q = quarterOfYear( 'April' );
// returns 2
q = quarterOfYear( 'apr' );
// returns 2
```
## Examples
```javascript
var quarterOfYear = require( '@stdlib/time/quarter-of-year' );
var months;
var q;
var i;
months = [
'January',
'February',
'March',
'April',
'May',
'June',
'July',

for ( i = 0; i < months.length; i++ ) {
