Hi @JPSS,

// Create a GlideDate object for the specified date
var inputDate = new GlideDate('2023-10-24');

// Create a GlideDate object for January 1st of the same year
var januaryFirst = new GlideDate(inputDate.getYear() + '-01-01');

// Calculate the difference in days between the input date and January 1st
var dayOfYear = inputDate.subtract(januaryFirst);

// Add 1 to account for January 1st itself
dayOfYear += 1;

// Display the result
gs.info('Today ' + inputDate + ' is ...');
gs.info('Day ' + dayOfYear);

If my answer has helped with your question, please mark my answer as accepted solution and give a thumb up.

Thanks,

Hello,

I don't think there is a Glide method for that, but you can achieve it with the JavaScript native Date object. Look at the code below:

var today = new Date();

var dayOfYear = Math.floor((today - new Date(today.getFullYear(), 0, 0)) / 1000 / 60 / 60 / 24);

gs.info(dayOfYear);

with Glide method is it possible

Late to the party, but in case anyone else is looking for an answer on this.  I got this to work:  

var gdt = new GlideDateTime();
var startOfYear = new GlideDateTime(gdt.getYear() + "-01-01 00:00:00");
var dayOfYear = gdt.getNumericValue() - startOfYear.getNumericValue();
dayOfYear = Math.ceil(dayOfYear / (1000 * 60 * 60 * 24));
gs.info('Today is day ' + dayOfYear + ' of the year.');
