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!

secondsInMonth

Determine the number of seconds in a month.

Usage

import secondsInMonth from 'https://cdn.jsdelivr.net/gh/stdlib-js/time-seconds-in-month@deno/mod.js';

secondsInMonth( [month[, year]] )

Returns the number of seconds in a month.

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.

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).

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 object.

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

Notes

• 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.

Examples

import secondsInMonth from 'https://cdn.jsdelivr.net/gh/stdlib-js/time-seconds-in-month@deno/mod.js';

var v;
var i;

for ( i = 0; i < 2021; i++ ) {
    v = secondsInMonth( 'feb', i );
    console.log( 'In the year %d, February has %d seconds.', i, v );
}
