Jira calculation of working days

[Johna.S.Lee]

Our sprint is 2 weeks (10 working days).  I notice Jira calculates 2 weeks span as 9 working days even when there is no holidays configured in that 2 weeks.  Pls refer to the screenshot below.  Pls advise about how Jira calculates working days.  Pls note it does not make any difference when I changed the starting time to8 am in the morning; still 9 working days.

That seems like 10d to me...

30, 31, 1, 2, 3, 6, 7, 8, 9, 10

Jack, I agree. But Jira says 9 working days (screenshot included). I can't figure out why.

Hi @Johna.S.Lee and @Jack Brickey 

I found this post, which matches some open defects/suggestions, indicating that the wording should be "remaining days" and not "working days", as the last day does not count when the units are "remaining days":

https://community.atlassian.com/t5/Jira-Software-questions/Incorrect-number-of-days-calculated-when-starting-sprint/qaq-p/1567831

Seems more likely to confuse teams setting up sprints which are not starting "today".

Snarky aside: Or perhaps a project manager designed the dialog and sees scrum agile events as non-value-adding, and so subtracted them from "working days"  ;^)

Best regards,

Bill

Ah yes I see where the confusion lies. I never have liked how this is presented.
