How to create a dynamic link to the calendar

I'll bet there's documentation out there to answer this question, but I haven't been able to find it.

I have event entries for several categories. I'd like to make menu links to the event calendar that calls it with filters pre-applied. For example, the Sales Department could link to a calendar showing only Sales Department events, the Production Department could have a link showing only Production Department Events, etc.

I see that you can expose the filters and have the user choose terms, but that's not what I'm looking for. I'm looking for a link that goes directly there. I understand that if I link to the calendar with event/yyyy/mm/dd/calstyle/nodetype/termid I'll get what I want, but I can't figure out how to make the yyyy/mm/dd values dynamically reflect today's date.

I'd be content to create views for each department if I could get them to link to events month style, but the event calendar wasn't available as an event view type, even though I had enabled event_views. So I installed Calendar, but now I'm at a loss for how to work with the arguments.

I feel like I must be missing something really obvious. Thanks in advance for any pointers in the right direction!
