In the next day or so, you'll start to see some changes to the event page in Google Calendar which should make scheduling events easier. We've made the style more consistent with other Google apps, put information that’s most commonly used at the top of the screen, simplified the layout, and added some functionality.

A new repeating event editor
The old interface for creating recurring events was clumsy and took up too much space on the screen. Now you'll see only a summary of your recurring event on the main event page; if you want to edit it, you can use a window that opens when you select the "Repeats" checkbox.

A new tool to help you find a time for your event
You'll notice a new tab on the event page that should make it easier to find a good time to schedule an event. When your friends or coworkers give you permission to see their calendars, you can click this tab to see a preview of their schedules and hover over their events to see what conflicts they might have. This should make scheduling a tad easier, especially for events with large numbers of guests. For Google Apps users, the new schedule preview can also show data from other calendar services using our Google Calendar Connectors API.

Changes under the hood
As browsers and other technologies both within and outside of Google have evolved, we've found it necessary to occasionally make structural code changes in order to keep up. These visible changes are only the surface; underneath we've added a new model for how we represent calendar events in the browser and a new mechanism for how we make sure those events get properly saved. We've paid special attention to performance, consistency, and extensibility. In the short term, you'll hopefully notice that the event page opens slightly faster than it did before.
