Why are there black dots in my hosting calendar?

You may notice black dots in your Airbnb hosting calendar over some dates. Hosts ask:

What are the black dots on my airbnb calendar?

The dots highlight popular dates. If you click on that date, the little black dot expands to show that it’s a popular date and you could raise the price if you want to.
