How are days in column calculated on the kanban Board?

[RL]

Does the day increase as the issue hits 24 hours old or does it flip at 00:00?

I suppose I could create a dummy issue and watch.

Hi @RL 

I recall the "days in column" feature sums the total time a work item is in a column based upon the changelog history.  Thus, it adds up the time and divides by a 24 hour day.  This time could include a work item being in a column, leaving it, and returning again later.

Kind regards,
Bill

I suspect you are right. I will move it midday and to two other columns and see the day count then

My experiment flipped 24 hours after I created the ticket and not before
