Vlookup multiple values to be shown

Hi guys

I need to create a project plan where we see on a calendar which projects are on which date. I managed to do this with Vlookup on my own, but the problem is that it only shows the first project on that date.

I need it to show all projects that are on that date, not only the first one. Attached you find a very simple version of my project plan, maybe someone can help me? As you can see on 01.01.2019 it only shows Project 1, but it should show Project 1 and Project 3 as they are both on the same date.

Would really appreciate some help on this!

Best regards
