Question

I\'m trying to create an array of times (strings, not Date objects) for every X minutes throughout a full 24 hours. For example, for a 5 minute interval the arr

Answer 1

You need only one loop, follow this approach

var d = new Date(); //get a date object
d.setHours(0,0,0,0); //reassign it to today's midnight

Now keep adding 5 minutes till the d.getDate() value changes

var date = d.getDate();
var timeArr = [];
while ( date == d.getDate() )
{
   var hours = d.getHours();
   var minutes = d.getMinutes();
   hours = hours == 0 ? 12: hours; //if it is 0, then make it 12
   var ampm = "am";
   ampm = hours > 12 ? "pm": "am";
   hours = hours > 12 ? hours - 12: hours; //if more than 12, reduce 12 and set am/pm flag
   hours = ( "0" + hours ).slice(-2); //pad with 0
   minute = ( "0" + d.getMinutes() ).slice(-2); //pad with 0
   timeArr.push( hours + ":" + minute + " " + ampm );
   d.setMinutes( d.getMinutes() + 5); //increment by 5 minutes
}
