Hi Paul,
I can confirm for you that currently calendar reports do not support dynamic filters like some other report types do. Mark is correct that you can prompt some filtering when someone opens the calendar using an ask the user filter. If you find that dynamic filters on a calendar report would be helpful to you I would suggest adding that to our User Voice. User Voice is a tool our product team uses to collect suggestions from customers on new features and enhancements to existing features. The Quick Base User voice can most easily be accessed from the My Apps page in Quick Base by clicking on the orange Feedback tab that appears on the right of the page or at
http://quickbase.uservoice.com by signing in with your Quick Base credentials. If you do place your feedback in User Voice I would suggest dropping a link here to it so that other community members with the same need can show their support. Thank you for reaching out Paul and sorry there isn't a built in setting I can point you to for that at this time.
