How to convert regular date to unix timestamp?

Question

css

Hello. Can you please tell me how to translate a date like "09/05/2017" is added using datapicker to unix timestamp?

There are two dates the patient needs to transfer these dates to unix and calculate among themselves.

PS All this is on jquery, something doesn't work for me ((

Answer 1

var date = "05.09.2017";
   var timestamp = new Date(date.split(".").reverse().join(".")).getTime();

Answer 2

Here is a unique function to convert normal date to unix

function ToUnix(dateArg = {
  str:false,
  Y:"1970",
  m:"01",
  d:"01",
  h:"01",
  i:"00",
  s:"00"
}){
  Object.entries(dateArg).forEach(([k,v])=>{
    if (Number.isInteger(v) && v < 10) {dateArg[k] = "0"+v}
    if (!Number.isInteger(v) && v.length == 1) {dateArg[k] = "0"+v}
  })
  let dateStr = `${dateArg.Y}-${dateArg.m}-${dateArg.d}T${dateArg.h}:${dateArg.i}:${dateArg.s}`;
  if (dateArg.str) dateStr = dateArg.str;
  return +new Date(dateStr);
}

Usage example:
asaToUnix({Y:1980,m:10,d:01,h:02,i:00,s:08}); //339210008
asaToUnix({str:"1981-01-02T10:10:05"}); // 347274605
