function was working, now nothing

[mdaniel1]

I finished a button click function that would alert with the time and date, it was working. I saved, closed notepad+, came back later and now when I click nothing, no error codes at the bottom, nothing, no response.
the button click is

onclick="ShowDate()"

the function is

function ShowDate() {
 var thetime = new Date();
 var weekday = thetime.getDay();
 var themonth = thetime.getMonth();
 var thedate = thetime.getDate();
 var theyear = thetime.getFullYear();
 var hour = thetime.getHours();
 var minutes = thetime.getMinutes();
 var seconds = thetime.getSeconds();
 var ap = (hour >= 12) ? 'p.m.' : 'a.m.';
 var someday = new Array(7);
 someday[0]="Sunday";
 someday[1]="Monday";
 someday[2]="Tuesday";
 someday[3]="Wednesday";
 someday[4]="Thursday";
 someday[5]="Friday";
 someday[6]="Saturday";
 var somemonth = new Array(12);
 somemonth[0]="January";
 somemonth[1]="February";
 somemonth[2]="March";
 somemonth[3]="April";
 somemonth[4]="May";
 somemonth[5]="June";
 somemonth[6]="July";
 somemonth[7]="August";
 somemonth[8]="September";
 somemonth[9]="October";
 somemonth[10]="November";
 somemonth[11]="December";
  
 if (hour < 1) {
   hour = 12;
   }
 if(minutes < 10){
   minutes = "0" + minutes;
   }
 if(seconds < 10){
   seconds = "0" + seconds;
   } 
 if(hour > 5&&hour < 12) {
   window.alert('Good Morning! Today is '+someday[weekday]+', '+somemonth[themonth]+' '+thedate+', '+theyear+'. The time is '+hour+':'+minutes+':'+seconds);
   }
 if(hour > 12&&hour < 19) {
   window.alert('Good afternoon! Today is '+someday[weekday]+', '+somemonth[themonth]+' '+thedate+', '+theyear+'. The time is '+hour+':'+minutes+':'+seconds);
   } 
 if(hour > 19&&hour < 5) {
   window.alert('Good Evening! Today is '+someday[weekday]+', '+somemonth[themonth]+' '+thedate+', '+theyear+'. The time is '+hour+':'+minutes+':'+seconds);
   }
 }

Your code will only work from 6 - 11 and 13 - 18 o'clock.
