Thank you for your submission. Can you add more information in the description? From your code and the title it now seems you are calculating the difference between two dates. There is already a function available "GlideDateTime - subtract(GlideDateTime start, GlideDateTime end)" to do this, documented in the docs here:
https://www.servicenow.com/docs/bundle/zurich-api-reference/page/app-store/dev_portal/API_reference/GlideDateTime/concept/c_GlideDateTimeAPI.html

It returns a GlideDuration -> Duration difference between the two specified dates.

Example:
var gdt1 = new GlideDateTime("2011-08-28 09:00:00");
var gdt2 = new GlideDateTime("2011-08-31 08:00:00");

var dur = GlideDateTime.subtract(gdt1, gdt2); // Difference between gdt1 and gdt2
gs.info(dur.getDisplayValue());

Output:
2 Days 23 Hours

I am closing this PR for now.

Description

This function calculates the difference between two dates and returns the result in calendar components:

• Years
• Months
• Days

While GlideDateTime.subtract() returns a GlideDuration object (e.g., 2 Days 23 Hours), it does not provide a breakdown in calendar units like years, months, and days.
