var hoursInYear = require( '@stdlib/time/hours-in-year' );

hoursInYear( [value] )

var num = hoursInYear();
// returns <number>

By default, the function returns the number of hours in the current year (according to local time). To determine the number of hours for a particular year, provide either a year or a Date object.

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

num = hoursInYear( 2000 );
// returns 8784

num = hoursInYear( 2017 );
// returns 8760

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 hoursInYear = require( '@stdlib/time/hours-in-year' );

var v;
var i;

for ( i = 0; i < 2021; i++ ) {
    v = hoursInYear( i );
    console.log( 'The year %d has %d hours.', i, v );
