Date field!

Default How to use TrimMean as an agregation function

Is the data really in a single vertical column ($A) as shown in your post,
or is it in a list across columns $A:$E? If it is in a single column, then
you will need to transpose it into a list format first. Then...

1. Build a pivot table from this data on a new worksheet.
2. Arrange the pivot table so that the Date is in a row area of the pivot
table (column $A), Hour is in the column area, and the HourlyValue is in the
data area.
3. Build the TrimMean formula in cells adjacent to the pivot table on the
right.
