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!
Determine the number of hours in a month.
npm install @stdlib/time-hours-in-monthAlternatively,
- To load the package in a website via a
scripttag without installation and bundlers, use the ES Module available on theesmbranch (see README). - If you are using Deno, visit the
denobranch (see README for usage intructions). - For use in Observable, or in browser/node environments, use the Universal Module Definition (UMD) build available on the
umdbranch (see README). - To use as a general utility for the command line, install the corresponding CLI package globally.
The branches.md file summarizes the available branches and displays a diagram illustrating their relationships.
To view installation and usage instructions specific to each branch build, be sure to explicitly navigate to the respective README files on each branch, as linked to above.
var hoursInMonth = require( '@stdlib/time-hours-in-month' );Returns the number of hours in a month.
var num = hoursInMonth();
// returns <number>By default, the function returns the number of hours in the current month of the current year (according to local time). To determine the number of hours for a particular month and year, provide month and year arguments.
var num = hoursInMonth( 2 );
// returns <number>
num = hoursInMonth( 2, 2016 );
// returns 696
num = hoursInMonth( 2, 2017 );
// returns 672A month may be either a month's integer value, three letter abbreviation, or full name (case insensitive).
var num = hoursInMonth( 2, 2016 );
// returns 696
num = hoursInMonth( 'feb', 2016 );
// returns 696
num = hoursInMonth( 'february', 2016 );
// returns 696The function also supports providing a Date object.
var num = hoursInMonth( new Date() );
// returns <number>- 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.
var hoursInMonth = require( '@stdlib/time-hours-in-month' );
var v;
var i;
for ( i = 0; i < 2021; i++ ) {

console.log( 'In the year %d, February has %d hours.', i, v );
}To use as a general utility, install the CLI package globally

696@stdlib/time-hours-in-year: determine the number of hours in a year according to the Gregorian calendar.
This package is part of stdlib, a standard library for JavaScript and Node.js, with an emphasis on numerical and scientific computing. The library provides a collection of robust, high performance libraries for mathematics, statistics, streams, utilities, and more.
