secondsInMonth

Determine the number of seconds in a month.

Installation

npm install @stdlib/time-seconds-in-month

Usage

var secondsInMonth = require( '@stdlib/time-seconds-in-month' );

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

var secondsInMonth = require( '@stdlib/time-seconds-in-month' );

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 );
}
