Google's new calendar design leaks, showing off the future of Android
Besides the new look, Google Calendar adds a Daily Agenda feature, which allows you to email the current day's schedule. Important parts of each day's appointments will be color-coded, and the update adds birthday reminders for the calendar view. Another section will list upcoming birthdays of your Google+ friends. Circles will now highlight each day of the month, which you can see for yourself in the screenshot found at the bottom of this page.
It is unknown whether this is the final version of the update, but those who have used it have been impressed.
