Determine the day of the quarter.

Usage

var dayOfQuarter = require( '@stdlib/time/day-of-quarter' );

dayOfQuarter( [month[, day, year]] )

Returns the day of the quarter.

var num = dayOfQuarter();
// returns <number>

By default, the function returns the day of the quarter for the current date (according to local time). To determine the day of the quarter for a particular day, provide month, day, and year arguments.

var num = dayOfQuarter( 12, 31, 2016 );
// returns 92

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

var num = dayOfQuarter( 12, 31, 2016 );
// returns 92

num = dayOfQuarter( 'dec', 31, 2016 );
// returns 92

num = dayOfQuarter( 'december', 31, 2016 );
// returns 92

The function also supports providing a Date object.

var num = dayOfQuarter( new Date() );
// returns <number>
