How to manage a scripted field based on a Date Picker field ?

[support for vo]

Hello Atlassian Community, I'm asking you today because I'm stuck on the script of a scripted field (I'm using ScriptRunner).

Here is my usecase :

A "Start date" (Date Picker) field is diplayed on my ticket and I have created a "Week Number" scripted field, also displayed on this ticket.
I would like to retrieve format "W25 2022" on Week Number field based on the Start date.
I have started some script on the Week Number field :

import com.atlassian.jira.component.ComponentAccessor
import com.atlassian.jira.issue.Issue
import static java.util.Calendar.WEEK_OF_YEAR
import static java.util.Calendar.YEAR
import java.sql.Timestamp

Issue issue = issue
def customFieldManager = ComponentAccessor.getCustomFieldManager()

// get Start date custom field
def date1 = customFieldManager.getCustomFieldObjectByName("Start date")

// get Start date value
def date1Value = issue.getCustomFieldValue(date1) as Date

// create Week Number custom field
def date2 = Calendar.getInstance()

// copy in Week Number the Start date value
date2.setTime(date1Value)

// transform date2 into format "WeekWW YYYY"
return (issue.getCustomFieldValue(date2) as Timestamp)?.toCalendar().get("WEEK_OF_YEAR", "YEAR")

 If anyone has any idea on this topic, it will be appreciated :)

Hi @support for vo 

if you just need a value of format WeekWW YYYY, you can use this code 

def date1 = customFieldManager.getCustomFieldObjectByName("Start date")

// get Start date value
def date1Value = issue.getCustomFieldValue(date1)

Calendar cal = Calendar.getInstance()
cal.setTime(date1Value)


return ("Week" + cal.get(Calendar.WEEK_OF_YEAR) + cal.get(Calendar.YEAR))
