To get a view of all events on 30 days

To get a view of all events on 30 days

Hi :)
I am new with this wonderful plugin with Event Manager Plus pack.
I have a question about the "selected_datetime" short code, I would like the first date to be today and the second parameter to be today + 30 days (to have a view of events over 30 days).
It's possible ?
Thank you :)
