Hi,
One solution is to extract the date text from the date column.
Then perform Statistics on Column (menu Statistics->Descriptive Statistics-> Statistics on Columns..)with the newly created text date column as group.
If you can upgrade to latest Origin version, There is a nice app for this:

Hi,
Here is another method:
1. Extract the date from the first column by simply putting int(A) in F(x) column header. You need to set column type to date to show the Julian date properly.
2. Go to menu Worksheet->Remove/Combine Duplicated Rows, set col(B) as reference column and merge duplicate by average.
3. The result worksheet will show as below:
