Hello, @toneee!
Thank you for your time posting your inquiry.
You can adjust the period to display events from Event Calendar WD > Settings > General tab. Please use Period for List view option and select the necessary period.
It displays the events from the upcoming period, corresponding to the period you have selected. And next/previous buttons of the calendar let you display the events from previous or next period.
Hope this helps.
Thanks! Have a wonderful day!
