Extracting data depending on whether a date is a weekday or weekend

I have a column of data with a large amount of various unorganized dates (dd/mm/yyyy). Each of the dates corresponds with a time (hh:mm:ss) in an adjacent column.

I have to separate the time data into weekdays and weekends, likely by using two new columns - one column with the extracted time data related to weekdays, and the other with the weekend time data, with blanks where necessary.

I am just wondering if anyone knows how to do this? One method I attempted is that I have used the =WEEKDAY() function to number each day in a separate column, but I cannot extract the data from here.

Cheers.
