var today = new Date();
var date = today.getFullYear()+'-'+(today.getMonth()+1)+'-'+today.getDate();
// `date` is a Date object
const dayOfYear = date => Math.floor((date - new Date(date.getFullYear(), 0, 0)) / (1000 * 60 * 60 * 24));
// Example
dayOfYear(new Date(2020, 04, 16)); // 137var days = ['Sunday','Monday','Tuesday','Wednesday','Thursday','Friday','Saturday'];
var months = ['January','February','March','April','May','June','July','August','September','October','November','December'];
var day = days[ now.getDay() ];
var month = months[ now.getMonth() ];const d = new Date();
d.getMonth() + 1; // Month [mm] (1 - 12)
d.getDate(); // Day [dd] (1 - 31)
d.getFullYear(); // Year [yyyy]//Month -> 0= Jan, 11=Dec | myDate = 6 Dec 2019 10:45
var myDate = new Date(2019, 11, 06, 10, 45);
var dayInYear = Math.floor((myDate - new Date(myDate.getFullYear(), 0, 0)) / (1000 * 60 * 60 * 24));
