How would you go about determining how many minutes until midnight of the current day using javascript?

Answer 1

function minutesUntilMidnight() {
    var midnight = new Date();
    midnight.setHours( 24 );
    midnight.setMinutes( 0 );
    midnight.setSeconds( 0 );
    midnight.setMilliseconds( 0 );
    return ( midnight.getTime() - new Date().getTime() ) / 1000 / 60;
