Workflow Transition Post-Function Condition "Custom date" script

Question

I would like to populate custom date in date field.

Custom date calculated as below

=IF(OR(WEEKDAY(Date)=3,WEEKDAY(Date)=4,WEEKDAY(Date)=5,WEEKDAY(Date)=6,WEEKDAY(Date)=7),(Date+7-WEEKDAY(Date)+2),IF(OR(WEEKDAY(Date)=1,WEEKDAY(Date)=2),(Date+7-WEEKDAY(Date)+4),"0"))

Any help on using this logic using post function "Script Post-Function" or "Scripted (Groovy) operation on issue (JMWE add-on)"

Thanks

Thanks David. Yes, Date above is the current date and time.

You didn't answer my other question about what "Date" means, so I'll assume the current date. You'll just need to update the first line if you meant something else.

Date date = new Date();
int day = date.day;
if (day==0)
 day = 7;//Java/Groovy Sunday is 0
if (day >= 3)
 return date + 7 - day + 2;
else
 return date + 7 - day + 4;

Weekday expression mentioned is from excel. 1 - 7 as Monday through Sunday.

I am looking for some sample scripts to get started!
