Largest Gap Between Dates?
Hi . I have a column which contain dates. Is there a formula that would:
- Return the largest gap between the dates in the column?
- Return the dates?
My column contains dates of call logs. I want to see the largest gap that occurred (for example, we didn't call anyone for 7 days). I also want to see the two dates used to calculate the largest gap.
So for the above, the largest gap between dates would be between 01/05/24 and 01/30/24 (25 days).

You would need a few helper columns. One to record how many days until the next call and one to record how many days since the previous.
Next call:
=MIN(COLLECT(Date:Date, Date:Date, AND(@cell <> "", @cell> Date@row))) - Date@row
Previous call:
=Date@row - MAX(COLLECT(Date:Date, Date:Date, @cell< Date@row))
Once we can ensure these are working, we can move on to the next step of flagging start and end dates for the gaps.

My column is not a fixed length, dates are being added constantly. Is my only option to mofify the formula each time a new date is added?

@Paul Newcome thanks for the reply. My column is not a fixed length, dates are being added constantly. Is my only option to modify the formula each time a new date is added?

Also, the dates may not always be in sequence.

You would not need to modify any formulas as new rows are added. Both of the above formulas are written so that they can be applied as column formulas and should output a number on every row.
