You can directly use Google Calendar to your website.
If you are using Google I am sure you will find experts connected to their forums for any kind of support related to products.
For day view with Google Calendar you can refer Google Groups.

Hope this will be helpful !
Hello, thank you for your reply! The information you gave me is very helpful. However, I contacted some of them, and their customer service seems to be pretty slow like UpTo.... I haven't heard back from them. Do you personally use any of them and recommend specific ones? (Using Google Calendar is not my option at this point because it seems like it doesn't allow me to show it as "agenda" view.)
I guess I am wrong, it seems it's possible to show agenda view if I embed it directly from Google Calendar instead of going through Muse Widget (Google Calendar Pro by MuseGain). I'll look into that, too, but either way, I like the sophisticated look of UpTo calendars and that's what I am looking for at this point.... Thanks.
