Help sorting data from one tab into seperate tabs by date field

Hi everyone, I'm brand new to VBA. Any help is greatly appreciated.

I have a spreadsheet that is filled with log data of a sensor taken in three minute intervals over the course of the past several days. I've been manually selecting, copying and pasting into new tabs by each day. I'm going to have to do a lot of this so I was hoping there might be a way I could do this more efficiently.

To help make this more clear I've attached two files. Before and After.

I want to take the "Before" file and automatically turn it into the "After"

Thanks guys!
