Determine the number of hours in a month.
Installation
npm install @stdlib/time-hours-in-month
Usage
var hoursInMonth = require( '@stdlib/time-hours-in-month' );
hoursInMonth( [month[, year]] )
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 672
A 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 696
The function also supports providing a Date
object.
var num = hoursInMonth( 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.
