How to get date difference ?

[Chasovskikh Kirill]

Hello, friends!

{{issue.customfield_11111.diff(now).months}} - returns integer number of months. 

Is there any way to get float number of month?

Or can i get difference between 2 dates without year ? 

F.e. difference between 01/02/20 and 10/02/20 without year = 9 days

Thank you in Advance.

Calculating difference in dates... the devil is in the details. 

See this StackOverflow thread for various ways to do so: https://stackoverflow.com/questions/1555262/calculating-the-difference-between-two-java-date-instances 

Scroll down to find the more updated answers. I recommend the one using classes Instant and Duration.

thank you!

but is there any way to integrate java code to standart jira cloud without plugins?

The easiest way seem to be Script Runner plugin, as Jira itself doesn't provide a way to script.

Hi @Chasovskikh Kirill 

I don't see anyway that you would be able to do the second one. 

And what do you mean by "float number of months"?

hi! 

integer - 4

float - 4.5

Hi @Chasovskikh Kirill 

Adding onto John's answers and questions...

What problem are you trying to solve with fractional months?  The fractional values are not comparable for months with differing numbers of days 28, 29, 30, or 31, right?

For your question about just days-differences, do you mean you have two literal date values or that those are from issue fields?  If literal, try putting the dates into created variables first.  If issue fields, why not just do a days diff()?

Kind regards,
Bill
