About stdlib...

We believe in a future in which the web is a preferred environment for numerical computation. To help realize this future, we've built stdlib. stdlib is a standard library, with an emphasis on numerical and scientific computation, written in JavaScript (and C) for execution in browsers and in Node.js.

The library is fully decomposable, being architected in such a way that you can swap out and mix and match APIs and functionality to cater to your exact preferences and use cases.

When you use stdlib, you can be absolutely certain that you are using the most thorough, rigorous, well-written, studied, documented, tested, measured, and high-quality code out there.

To join us in bringing numerical computing to the web, get started by checking us out on GitHub, and please consider financially supporting stdlib. We greatly appreciate your continued support!

dayOfQuarter

NPM version Build Status Coverage Status

Determine the day of the quarter.

Usage

To use in Observable,

dayOfQuarter = require( 'https://cdn.jsdelivr.net/gh/stdlib-js/time-day-of-quarter@umd/browser.js' )

To vendor stdlib functionality and avoid installing dependency trees for Node.js, you can use the UMD server build:

var dayOfQuarter = require( 'path/to/vendor/umd/time-day-of-quarter/index.js' )

To include the bundle in a webpage,

<script type="text/javascript" src="https://cdn.jsdelivr.net/gh/stdlib-js/time-day-of-quarter@umd/browser.js"></script>

If no recognized module system is present, access bundle contents via the global scope:

<script type="text/javascript">
(function () {
    window.dayOfQuarter;
})();
</script>

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>
