How can I calculate the number of days between order n and order n+1 for each customer in Power BI?
I want to show and analyze the timespan*(in the day)* between first and second, second and third, etc orders.

Hi @KiKa ,
You can create a calculated column as below to get it:
Number of days =
VAR _nextodate =
CALCULATE (
MIN ( 'Table'[order date] ),
FILTER (
ALL ( 'Table' ),
'Table'[user id] = EARLIER ( 'Table'[user id] )
&& 'Table'[order id] > EARLIER ( 'Table'[order id] )
)
)
RETURN
DATEDIFF ( 'Table'[order date], _nextodate, DAY )
Best Regards

@KiKa , Try a new column like
New column =
var _max = maxx(filter(Table, [User Id] =earlier([User Id]) && [Order Id] < earlier([Order Id]) ),[Order ID])
return
datediff([order Date] , maxx(filter(Table, [User Id] =earlier([User Id]) && [Order Id]= _max ),[Order Date]) , Day)+1
Hey! I used your proposed solution above to solve a similar problem. However, the formula seems to struggle whenever the second order is in a new year or whenever a customer has placed two orders at the same day (see below example). In those cases it turns out negative.
this is how the formula looks like with my data
