JS / PHP，日期时间

Question

i would like to ask, if someone know to to make in JS or PHP time of date.

Or how long we're together, like 70 days or 2 month and some days, and all day add 1 more day. I have something whats work, but on begging of that time is - . I spent a lot time with making something what should work. But nothing.

There is that code with that -

  var day=      8 
  var month=    12 
  var year=    2016 
  var event=    "relationship with my ♥"
  var end =     "days of"


  var daystocount=new Date(year, month -1, day)
  today=new Date()
  if (today.getMonth()==month && today.getDate()>day)
  daystocount.setFullYear(daystocount.getFullYear())
  var oneday=1000*60*60*24
  var write = (Math.ceil((daystocount.getTime()-today.getTime())/(oneday)))
  document.write('<strong>'+write +'</strong> '+end+' '+event)
}

  daysTill();

</script> 

if someone know, please help me. Thanks ♥

Answer 1

The getTime() method returns the time in milliseconds so to convert it to days you divide that by 86400000 (1000 for seconds * 60 for minutes * 60 for hours * 24 for days):

var relationship = new Date("2016/12/08");
var today = new Date();
var days = Math.ceil((today.getTime() - relationship.getTime()) / 86400000);

document.write(days + " days have pass since the start of the relationship.");

</div>
