Hello,
I have a data sets with different "Location" codes, and for each location, it has different "IJ dates" under each location.

The date ranges from 05/01/2021 to 05/05/2021. I would like to join the two data sets and find out those missing dates for each hotel.

So ideally the outcome should be like this. Since BAKPH does not have 05/04/2021, and TYOCT does not have 05/01/2021 - 05/04/2021... and so on.

Just would like to see if anyone can help, thank you!!! 😁
