Look up and calculate the difference between two dates associated with an ID value

I have two columns of data, one a list of dates and the second a list of IDs. I want to calculate the difference between the date in the current row and the next largest date associated with the same ID. I am guessing that I will need to use DATEDIF, INDEX and MATCH but I am not sure how to put it all together. I guess that the final formula would resemble {=DATED IF(currentdate,(formula to find next date),"d")}.

I have tried using {INDEX(daterange,MATCH(ID,IDrange,0))} but this gives me the first date associated with the ID rather than the next largest date.

How do you find the next largest date associated with the ID value for the current date?
Any advice would be greatly appreciated, thank you.

Attach a sample workbook (not image).so that we do not have to manually key in your data to do a testing.

Make sure there is just enough data to demonstrate your need. Include a BEFORE sheet and an AFTER sheet in the workbook if needed to show the process you're trying to complete or automate.

Make sure your desired results are shown, mock them up manually if necessary.

Remember to desensitize the data.
