Can I schedule by hourly slots or evening instead of just AM/PM or whole days?
If you see the ‘Advanced’ link on the right of the calendars, you can click on that for exactly such fine-grained scehduling (right down to 15-minute intervals, in fact). If not, then this is either a restricted-capability version or you need to register/apply to have this capability (clicking on the faded link will take you to an explanation). Don’t forget that for many events, such as ‘get-together evening dinner’ or ‘the 8PM book group’, the time can be assumed in advance (or specified in your email invitation to participants), and thus only the date needs to be selected! Please ‘stay tuned’ for further announcements about making such features more widely available.
