How to calculate the day of the year

like 

Today Tuesday October 24, 2023 is ...
Day 297

[Niklas Peterson]

Hi,

Here is one way to do it. Take the difference between the day and the first day of the year and add one day.

var sgd1 = new GlideDate(); 
sgd1.setDisplayValue('2023-01-01'); 
var sgd2 = new GlideDate(); 
sgd2.setDisplayValue('2023-10-24'); 
 
var duration = GlideDate.subtract(sgd1, sgd2);
var dayNumber = parseInt(duration.getDisplayValue())+ 1;
 
gs.info(dayNumber);

Regards,
Niklas

This code works. But i need to have the year changed dynamically,Instead of hard coding

[Sai Kumar P]

Try this piece of code:

var currentDate = new Date();

// calculate the day of the year

var startOfYear = new Date(currentDate.getFullYear(), 0, 0);

var dayOfYear = Math.floor((currentDate - startOfYear) / 86400000);

gs.info("Today is Day " + (dayOfYear + 1));

OUTPUT:: 

*** Script: Today is Day 297

with GlideDateTime can we achive this instead of date
