Apologies if this isn't explained particularly well.

I have a table containing dates in column A and a number in column B. What I would like to do is average the numbers in column B based on the day and month in column A and for it to show the latest full date range.

So in the example below, the response would be 01/01/2020 and 12.5

01/01/201710
01/01/201815
01/01/201915
01/01/202010

This SQL will produce what you want:

Code:
SELECT Max(YourDateField) AS LatestDate, Avg(YourNumberField) AS AverageOfYourNumberField
FROM YourTableName
GROUP BY Day([YourDateField]), Month([YourDateField]);

As often happens, we think we know what we want then when a solution is provided we adjust our requirements :)

The above solution works as expected, but having looked at the results, I would like to exclude the day/month that falls is the current year from the calculations.

Give it a shot, see what you come up with and then post back here if it doesn't work.
